Super normal! Transition is a lot like speed running puberty. Cis women have had their childhood and teen years to try different styles of femininity and pick what feels right for them. Many of them don't wear nail polish or makeup. You don't have to have nail polish if you don't enjoy it, and it doesn't make you any less femme because of it.
Heck, I still have some leftover baby-trans clothes that I'd be really uncomfortable wearing now. I thought they were what I needed to wear to be femme enough when my dysphoria was still raw during early transition.
