I core and wash my tomatoes (if you aren't going to put them through a food mil or Victorio strainer, etc., you should scald them to take the skins off) then cut them into chunks. I put them in ice cream buckets or gallon freezer bags. When I'm ready to can tomato juice or sauce, I take them out of the freezer to process. If you are just going to can juice, they don't need to be completely thawed before putting them in the kettle. For thicker tomato or spaghetti sauce, it works better to thaw and drain off the "clear" liquid--otherwise it will take longer to cook down.I'm still trying to figure out what varieties work best for my family. In the past we've only really used tomatoes as slicers for raw eating or BLTs or whatever. So beefsteaks are a must. We also make salsa every year. I like cherry tomatoes occasionally for salads but I always end up with buckets of them and I might eat only a couple of salads all summer (something I'm trying to improve!). The rest just go to waste as my chickens aren't really fans. I *really* want to make and can my own tomato sauce. But I never seem to get enough tomatoes at the right time to do it. Last year I was saving tomatoes in the fridge but by the time I had enough to try to make sauce, many were moldy. I ended up losing the whole harvest.
You can wash your cherry tomatoes and freeze (strain). They will work fine for tomato juice.
Edited to add: I wouldn't to this to make salsa. I always use fresh tomatoes for salsa.
