Up to you of course, but yeah many people and most photographers would see a big difference between 2.8 and 4 in many situations. Sports photography is generally tough since pros use excellent lenses that are fast and long.

You have a DSLR camera and a Mirrorless camera lens. You can adapt a DSLR lens to work on mirrorless cameras but not a lens made for mirrorless to work on a DSLR. Generally.
Good news: you bought a cool lens! You could sell your older DSLR and get a new mirrorless Canon camera. OR you should be able to sell the new cool lens and buy a cheaper, older lens that works on your older canon dslr.
Lastly, I don’t do bunch of macro photography, but I would say that most folks who want to photograph insects use a longer macro lens than a 28mm allowing them to be a bit further away from the bug. Assuming you already researched that part ignore me, but if you didn’t then do research it.
