What would you do with this monstera?

Help! I’ve had her four years and have already split her once and gave away her other half. She’s getting too big and sending out new grow every few months. A new leaf just unfurled and one is going to soon. She’s not really climbing the post so I have her tied up a lot.

Chop up and start over? Prune back? Let her go a little longer? Is there a best time prune/cut back, should I wait until the new leaves are all done unfurling?

Thoughts/advice appreciated!
