This was a major struggle that we had when we were still on 5e, our solution was to curate a large collection of homebrew, and most of the players in our guild game (kinda like a west marches) who cared ended up leaning into casters. In fact now that I think back on it, a lot of the homebrew our players actually played with involved adding a variety of gish options that were more mechanically involved than the actual martials. I also did a lot of top of my head rulings for some players who didn't have the rules chops to buy themselves more interesting mechanics, though that could be kind of taxing in the middle of the session for me, and was eventually at odds with our desire for a balanced system.
Switching to Pathfinder 2e was a complete cure for us in the end, but that would obviously be a pretty extreme solution for you OP.
