Starting a keeper league next year. Help

I have been researching and I think it’s time to do it. None of my friends want to run it but they’ll do it. So I’m doing it.
Rule set:
12 team .5 PPR 4 Keeper (is that okay?)
QB, 3 WR, 2 RB, TE, FLEX, DEF. NO Kicker. 6 Bench 1 IR.
No divisions. 6 Playoff 6 Non-playoff. Non playoff teams are put in a lottery for top 6 picks. Im thinking the winner gets to choose his pick in the draft.
Any tips on scoring and the rest?

Maybe like a rule you cant keep your first round pick.

I’m not a fan of the winner getting to choose his pick in the draft if it’s a keeper league, cause then he/she will always have a great team.

I have a personal preference of 2 WR, 2 RB, 2 Flex but that’s just me. Allow FAAB to be tradeable.

Yeah I was thinking that too. But you never know what could happen.

I like the 3 WRs just cause it’s easy to cycle through them. I like tradeable FAAB. Is that on Yahoo?
