Auction draft, .5 PPR, RB1 as a keeper

Would love some advice on how best to work this auction with the below info:

12 man
16 players (QB, 2WR, 2RB, TE, W/T, W/R/T, K, DEF, 6 bench)
.5 PPR
Keeper league (I kept Derrick Henry for $31)
$200 bank

What do you think the best approach would be here? What would your ideal draft be here?

Target 2 more RB1s for ~$120, combined with Henry for 3 RB1s with about $50 left over?

1 more RB1 and a WR1 with ~$70 left over and some more to throw around mid rounds?
