I asked a similar question awhile ago, and someone pointed out that most of the small tool makers who use rechargeable batteries for their line of tools also sell cordless vacs. So, if you're already using one manufacturer's cordless drill/yard tools/etc, look into their cordless vac as well.

I can't speak to the buy-it-for-life quality, but I just bought a couch and loveseat from sabai.design. They seem really well-made, plus sustainable, made in the US, diverse ownership, etc. Anyway, I'm pretty dang happy with them so far.

Relatively inexpensive: Saddleback leather

Hella expensive: Ashland

Both should be BIFL, both full grain leather. Both have a variety of size options. Ashland's leather is technically nicer, but it's hard to justify the price difference in BIFL terms. I believe Ashland is made in the USA and Saddleback in Mexico. I've had both, recently upgraded to an Ashland after my Saddleback wallet was stolen. As I said, the Ashland is hella nice, but hella expensive.

Oh, and don't forget to treat your leather with a quality cleaner/polish about once a year.

I've got one from REI as well. Comfort and build-wise it's incredible. Everything looks very solid, but I've only taken it on a couple of trips, so I can't vouch for the buyitforlife qualities.
