For ways to skill up, there is remapping but that is very long term, 1 year of 1 type of skills., then switch for year 2.
Not intended to take pauses,. but intended to play without having max skills. This isn’t WoW / SWTOR where you are meant to level to max in 30 days / 24 hours, and then raid every night at Y o clock in order to maintain your ilvl that is increased every expansion. Originally in Eve there was nothing but attributes, and skilling up did take years - but it was really cool when you did get new skills.
Exploration is one of the good incomes, if you look back at missions fx, the very peak of that income is what you are already getting, so from an income perspective, it will only a be a downgrade.
If you want to get into FW, then dive in, avoid corps that expect you to P2W 200million SP to max skill before they will play with you, there ought to be some that take actual new players around still.
