Student Finance as EU settler

So Ive been living in the Uk since 2020 exactly 3 years now, im not sure if im on pre-settled or settled but its 1 of the 2. Im thinking of applying to both EU universities in my home country or a country with the same language so Belgium or the Netherlands and UK universities aswell. 2 reasons for that, as a Eu citizen I only pay like 1k a year excluding living costs and its kind of a safe option aswell because Eu universities as ive read accept anything above or equal to CCC in A levels so aslong as I pass i can go to an EU uni.

I have 2 questions:
1. If I decide to go to a Eu uni during results day because of my results or any other factor, where do I apply for student finance? The UK or my Home country?

2. how will my settled status be affected if I move out for 3 years and come back to the Uk only during Holidays?

Small edit of info i forgot:
- Im just finishing year 12 in 2 weeks
