It depends on what kind of playing you want to do. If it's heavy-duty orchestral or big band lead playing, I can't help you. If it's Jazz combo playing, I would look to Chet Baker for inspiration and guidance.
While recovering from getting his teeth bashed in, I know he specifically said playing long tomes. He alluded to "all the books". I assume he meant Arban, Williams and Clarke, etc.. But what I got out of his personal comments was a different approach to playing. He certainly could play with conviction but it was without the kind of aggressiveness of, say, a Lee Morgan.
He learned how to get his trumpet to speak, with little pressure. Of course there's no playing with absolutely no pressure, but I would explore the writings of the "no pressure" advocates and take what works best for you. Playing with false teeth did have an effect, not only on his playing but on his endurance, that's one reason he mixed his sets up with both playing and singing. So, if you can sing, sing and give your chops a rest. If you can't, program an occasional tune featuring ne of your band mates and you laying out. If you're playing alone, this doesn't apply.
I play with very little pressure and what helped me was a change in attitude about using an embouchure plus, using more embouchure and less pressure doing the Maggio exercises. n.b. I did not use Maggio's embouchure, just the exercises.
If you're a combo player, listen to Chet in Tokyo and tell me if that's not good enough,
