Maybe the most impact day-to-day is splurging ($10/mo) on the 2TB iCloud storage plan for the family. It's pretty much replaced Dropbox, One Drive, scp-ing files around, etc. I even use it on Windows.

Cheap Panasonic Ergofit earbuds. They fit my ears well and isolate me from a good bit of noise. With a Lightning adapter and some sleep sounds / music, they usually get me through any night noises. My Airpods Pro are much better for this but the battery can't get through the night.

I got a 45-watt Nekteck USB-C car charger which helps top off my laptops or iPad when I'm out roaming and working from different places. Had previously used an inverter and the normal charger but this is small and easy.

Little nondo USB-C to USB-A adapters. I'm up to either 6 or 8 of these now. It's just handy to keep them on USB-A devices and no noticeable 2.4GHz interference like other brands.

I got lucky on a $99 black friday deal on a Dell color laser a couple years ago. It's been almost perfect. No more dried out ink. We just finished the last original toner cartridge and can probably get 2+ years out of a $24 knockoff set and that's with a teacher and high schooler in the house.
