Tomato starter plants?

I'm going to attempt two larger containers this year in the backyard of my tiny house - one with a few herbs, and one with tomatoes.

I'd prefer mid-sized tomatoes like overly large cherries or roma, but i mostly just want the to taste good.

It's just me, so I don't need a bunch of them.

I have no clue what wildlife will try to eat them. Yard is fully fenced and two smallish dogs of mine regularly get let out to chase everything off, but still...

I don't want to nuture plants from seed just for them to get eaten. So, for this first attempt...(edit: 1st attempt here in my new STL house)

Where is a good place to get tomato starter plants that aren't tasteless? An heirloom or organic or non gmo?
