Exterior Insulation Options

I live in southwest Nebraska. Going to be tearing out old lath and plaster walls...which have some form of insulation (unsure at this time), and old wiring. I will be installing new wiring first, and then working on insulation. As of now, locally I have options of fiberglass bats with one side of paper backing, offering up to R-13 value. The other option is blowing in cellulose. However, I am not sure which insulation is going to be better?

I want to consider future proofing this job too. But first I am not sure how the blow in process would work if there is no drywall. I'm guessing some form of netting. Is there a specific product for this?

Is cellulose going to offer better insulation? (I know it's neater around pipes and wiring...but harder to do with firewalls if I decide to put them in)

My understanding is that cellulose settles over time. In 20-30 years from now I still want good insulation. Will Cellulose eventually become less R value than the current fiberglass that supposedly does not settle?

Just unsure of what is the better option...I welcome all opinions. Thanks.

What do you mean by future proofing?
