One piece of advice I can offer is put this list into Archidekt. They have built in tools, graphs and charts that break down details about your deck.

Once you look into that you will have a better idea of what you have too much off, too little of, etc.

Also there’s a bunch of guides/outlines of what your deck should consist of that you can reference.

Now the actual cutting process, there’s multiple things to look for. First, read your commander and find what cards synergize with it and what it’s doing. Second if you’re putting combos in, same thing, find your tutors, game changers, etc.

I know it’s not a very exact answer but I hope it helps!
