Welcome to the forum. Your first several posts are moderated, which means that they may take a while to show up, particularly if posted over the weekend. But stick with it and that passes quickly.
You are wise to think about something larger than the HO 4X8 if you want to build an island-style layout. 5X9 or 5X10 will offer more room for broader curves and more interest in not much more overall room (once one includes the aisles).
But if you are thinking of full-size passenger cars, note that these require larger radii (24”-28” or more, depending on brand). So these will push the end curves out fairly wide. There are “shorty” passenger cars available which run on smaller radii.
This HO 6X8 donut-style layout allows for broader curves on the outside oval and would benefit from being a foot longer. But it could certainly host passenger and freight trains.
A lot depends on your own preferences for era, locale, real-life railroads (if any), etc. If you post some of those ideas, others may have additional suggestions for you.
Best of luck with your layout.

In your pile of books, do you have the Kalmbach plans books? Westcott's classic book has a number of 4X8 plans. And yes, it is possible to have both passenger and freight on most of these plans, especially if you are into the pre-60's era, when the equipment was way shorter. In other words, running heavyweight passenger cars exceeding 80' is not really a good idea on a small pike. It would not look good and operations would be quite limited.

Dan,
1. Welcome to the forums!
2. My comment is from far left field, so feel free to ignore me!
Are you hooked into HO? (Lot of equipment, track, etc?)
If not, have you considered N Scale? On a 4' X 8', you can get a lot of N Scale layout into that size, including longer passenger cars.
I'm 67 and just started my first layout last year. I, too, have a smaller area for the layout, and I've been able to fit long N Scale trains and long passenger cars with no problems.
Good luck with whatever you decide to do with your new layout!

30 years ago, I chose Roundhouse Harriman passenger cars, which fit the same era and work for me. They are still available on Ebay.
Byron is our track planning guru. His open center design allows you to easily reach all sections to scenic or address derailments. However at a certain age, crawling under the layout is no longer enjoyable.

For a 4x8, if you want decent operation ability, Id suggest N scale. In HO a 4x8 would limit you to sharp curves 18" R inner and 22" R outer. Scale length passenger cars really need 24" R or greater. Those same curves in N would be quite generous for longer cars.
I'm not a track planning software guru or do it for a pay, but have been interested in layout design for about 30 years and have always enjoyed studying track plans. I do all my layout design old school with scale rule, graph paper, compass, eraser shield etc.
There is a nice N scale book by Atlas called Nine N Scale Railroads you might want to take a look at. I still have my early edition copy. There are other track plan books and many premade plans to look at and get an idea for what you might like.

Make sure you use large wheels - I use 4" wheels on my 5'4" x 12' rolling layout and 5" would be better. The larger wheels roll much easier than the small ones - I tried some 3", they roll but not easily.
Oh and don't use wheels with the locking mechanism - unless you have quite a slope the locking isn't needed and tends to lock up at the wrong time.
If you can increase the size beyond 8 ft don't put the legs at the end. Assuming you are using 1x4 lumber, I have found that longer than 8' spans tend to sag over time. On my table the legs are 32" from each end which is a little less than 7' apart. Use diagonal bracing to support the ends.
Realistically, your best bet is a double track oval with 22" out radius and an inner track radius of 19 1/2". If doing sectional track you can space out 18" with their short pieces of straight at the mid point of the 180 degree end curve or just accept 4" centers (this reduces what you can do in the interior).
Since you're planning on having it rolled up against a wall, put all your turnouts in the front for easy operation in the against the wall operation.
Increase the basic table as much as possible to broaden the curves and provide a longer straight away. If you don't put track in the center 2 feet you can go up to about 6' wide.
Good luck

Hi folks,
Hello All,
If you could expand to a ping-pong table size (5'x9') this would expand your HO scale possibilities.
DanGray...run both freight (75%) and passenger (25%) on a 4x8...
What kind of industries are you thinking about serving with the freight line(s)?
A single industry focus; logging, coal, grain, cement, etc. or many smaller industries?
On a smaller pike in HO you might be limited to 4-axle diesels or steamers no larger than 0-6-0's. Also, rolling stock could be limited to no more than 50-feet.
What kind of passenger service are you considering?
Narrowing down your goals might help you out of the "Analysis paralysis".
Keep the questions coming.
Hope this helps.

Just an idea; You said something about a shelf layout,but are concerned about water heater ect.
If you ran the shelf up to the whatever, you could use a pieace of 1X6 as a liftout to get past the whatever.
I did it once to get around the furnance, simply lift it out when needed.
If planning on getting close to water heater, circuit breaker panel, etc please check local building codes. When a water heater dies they need a certain amout of room for changing it. Electric panels are covered by code. Furnace needs room to repair/replace.
