Does it make sense to consolidate UTXOs at this time, given the relatively high network fees? How much sats/vB should be enough – will 1sat/vB be stuck for weeks and weeks on end?

Or should I just wait it out till it's all back to normal? Median fee on mempool.space is ~22 sats currently.

I'd use Sparrow or Electrum. Have around 30 UTXOs
