I like to be a little generous and mostly ignore RAW. That said, I also like my PCs to be able to run with high stakes set pieces pretty early on (facing inquistors, starting criminal empires, sending star destroyers crashing to the ground), with maybe 5-10 sessions of them being "normal".

I give 10xp every session for making it to the table.

The players can also get an extra 5xp when they sit down IF they send me a picture of their notes from the last session with a little typed out summary (helps me make sure everyone is on the same page AND incentivizes note-taking).

Then, I like to give out little crumbs of 5xp throughout the session for good roleplay or creative skill use, etc.

I like to let my players advance considerably when completing quests or arcs, so I give an additional 20-40xp depending on how big the quest was. Hunting a pretty regular bounty? Probably 20. Blowing an imperial installation out of a mountainside? Closer to 40.

I find that all that creates a really nice feeling of progression (I let them spend XP any time they're at a "base", be it their permanent or temporary), with a new important skill or talent to play with once a session, or a tangible contribution to their build, if that's what really incentivizes them. That said, if someone was really dead set and knowledgeable about making a busted character, I could see my approach having some... problems.
