Too many monsters: what to do?

All of the above are good reasons.

Pick any and you and the players win.

I use monsters from the MMI only. I sometimes rename them, and change their appearance, but it really is a monster from the MMI. I look in the chart in the back with CRs listed look up the type of monster I want and then just take those stats for whatever I'm throwing at the party.
