Have you thought about growing the dwarf indeterminate tomatoes they’ve developed over the past 4 or 5 years?
Those do great in containers but they make continually and not just once and then kinda enh the rest of the summer.
Here’s a link to some of them:

Other places carry other varieties of them too. Sandhill Preservation had some last year, didn’t think to look for them this year.

I see a few on there. The ‘Tricot Czech’ one isn’t an indeterminate one though, but the Perth Pride one is.

If you search for ‘dwarf tomato project’ you may find others.
A pepper I’ve had good luck with in containers (and in the garden too) is ‘Albino Bullnose’. I got mine from Baker Creek. It got about 24” tall by early Nov and was loaded with bell peppers. These are the smaller 1980’s size bell peppers, not the ginormous ones you get at the grocery store. For stuffing they’re perfect. Ditto cutting up for salads, tacos, pizza, etc. They start off sort of a cream color and progress through orange to a dark orange/red color. So they’re pretty too.

Thanks for all that info. Now I have something to do tonight other than watch a race. Around here, patio tomatos are a big seller for containers, but I have not tried them.
