I recommend going for 65% instead, especially if you bind left windows key into FN it is very convenient, I thought I needed F keys and tried smaller layout out of boredom - I will never get anything bigger than 65% again, I think you should just consider this
Your budget is very high, what type of quality are you really looking for? It would make sense to buy the boards you have mentioned if you don't like flex cut pcbs or you already know what type of mounting style you enjoy.
I would buy Womier SK75 personally it is way cheaper and I assume you already have key caps? You can find different plates for it as well if you don't like stock one.
If you really want to stick to your picks that is up to you but I think these days there is not that much difference between "budget" and high end boards, if I were you I'd rather spend that money finding perfect setup of switches/key caps/plates
