Need help with installing custom OS on samsung Phone

[CalmCreeper360]

Date: 2 January 2023
Device: Samsung A20e
Problem:

I want to install a custom OS on my phone to debloat it.
Id like it to be a bit 3D/Skeumorphic or at least to be customizeable to be so.
I also want it to be bloat (google/meta) free.
What are my choices?
Which sites are to be trusted when downloading a custom rom?
I need some advice cuz i know 0 about phones.

Thank you

I would look on XDA, there's a category for the A20x series.

I would look for a LineageOS (or LineageOS based) ROM. All of the ROMs will be flat but you could use a custom launcher with a skeuo icon pack.
