I think it matters who does the fit ,
I had a fit done once and it was just an opportunity for the bike shop to sell you stuff you didn't need
stem is too long, need a shorter stem, cleat is wrong, new cleat, this needs a shim, buy this one
don't think there is any way better than doing it yourself , if you make an adjustment , ride with that set up and adjust accordingly
eventually you will get it right, I don't think a fitter can do that for you. close but not right
there's plenty of material online to see what is the best position, set it up , the rest is up to you to adjust.
you will have a better understanding of bike positioning in the end,
to me it is super interesting to adjust and get things better. it does take time.
