Making the iPad part of my interOS lifestyle

Hi all - the last Apple product I purchased was the gen2 iPod. I have a decade old iPad that I inherited from work and never really used - right now it's an always-on authenticator app screen at my desk. I have used MacBooks of all flavors for work for the last 12 yrs and have inherited both Air and Pro for personal use. My primary PC is Windows. My servers and NAS are Proxmox and Linux. Android phone user since switching from Blackberry, and have a matching tablet that isn't super new and is mostly controlling yt music streaming to the office tv roku, and/or keeping up a calendar app. Personal and work on Google apps and storage. Lots of nerdy stuff going on here - house runs on Google Nest Hubs, rPI Home Assistant, SmartThings, Hue, and others; Stream Deck and the usual wfh streamer tech at the desk.. I'm pretty much using everything except iOS (except for my "authenticator touchscreen").

My child has been on a 9th gen iPad for the last yr. I grabbed one for myself a cpl wks ago when the price bottomed out. I've setup the airdisplay with my work laptop during the day but it doesn't stay open persistently and I have a ton of monitor workspace anyway so that hasn't really worked for me. I'm used to grabbing my phone when I'm bored, hit the restroom, need a break from work. I used to open Reddit - now I open Lemmy occasionally but not as much.

What do I do with this thing? People using other platforms primarily, what is special about the iPad to you? When do you grab it instead of another device?

I've tried to find articles, videos, tips, etc. - but everything is either migration, comparison, or beginner tips for iOS. I'd love to understand what others are doing in my scenario.
