Worth noting that there is a distinct group of Facebook saddle fitter posters that abhor anything French saddle. They detest the short tree points. I am not educated enough to know the science, but I do believe my horses tell me when their saddle fits. I have had French saddles that fit, and French saddles that don’t. I suggest getting your education from persons who do hunter/jumper not just dressage.
I have a local saddle fitter come tell me generally what to look for. Does my horse have a flat back, curvey back, is he wide, narrow? She can sometimes suggest a make and model. Then I go to my favorite saddle resellers and send pictures. There are some out there that work really well from photos. Then I get trial saddles and let my horse inform me. Then maybe a final blessing from my fitter. It’s a proces, but worth it.
