How would you guys tackle this wall?

Knock off the high spots with a 6" taping knife.
Float over the low spots with a 12" knife using lightweight joint compound.
Let dry.
Determine whether you will need a second coat.
If no, sand, prime, and paint.
If yes, knock of high spots/lap marks with 6" knife and coat, dry, sand, prime, and paint

Need to cover up the inaccuracies? Looking for some solutions. Thanks in advance!

Fill it with a think coat of compound then sand till smooth.
