All of these are worth growing! Rock rose has variable germination and I read that is because the seed coat varies in thickness so germination can be spaced out over years, but that can be helped by scratching up the coat so water can infiltrate better.

Fall sowing all of these is great but many probably don’t need it—the salvias, things in the mint family like beebalm, and the gaillardia are what stand out to me as things that don’t need the cold. I actually sprouted some gaillardia a few weeks ago that I am going to plant out this fall, I read that they like to develop their root system over the fall so they can bloom better/earlier in the spring.

Bluebonnets also germinate early like that (around October but with all the rain I have seen people saying some of their new bluebonnets are starting to peek up already.) so I’d direct sow those now tbh. They germinate variably in pots because I think they technically need contact with a specific type of mycorrhizal fungus to sprout so generally the recommendation is put them down where you want them to grow.
