At the moment when buying something on chain and the change is small, I line it up with a LN swap or liquid peg in. That way I'm avoiding future onchain dust. 

This is exactly the thought process I have been going through.

What's the Smallest Unspent Transaction Output (UTXO) a Bitcoiner Should Have?

Its hard to know. People freaking out about fees (I'm one of them!) can't really say that we're going to have a dead mempool again. 

100k sats for this epoch sounds about right, but long term I think 1 million sats should be good standard to go by. 

Lightning and other L2's are not ready for mass adoption yet. A lot of OG bitcoiners only transact on chain so it will take time for them to move up a layer or 2.

Then there's the whole issue of consolidating UTXO's and sacrificing privacy which is not ideal either.
