I also use it to create routes for road trips for my Jeep club: it's really nice to have my GPS app and a satellite view side by side as I look for interesting back roads.
In short: I bought a Ferrari and use it like a Civic.
I keep computer science/math-related PDFs in Dropbox, copy them to GoodReader (I've started experimenting a bit with other PDF apps, but GoodReader has been my go to for years now), and occasionally use Apple Pencil to mark them up as I read them. I don't save them back to Dropbox for future review; GoodReader is effectively its own island in that regard.
For GPS, I use Gaia GPS to create routes, often with Apple Maps and/or Google Maps running in split screen.
If you have specific questions, I can address them, but none of it is particularly formal.
LiquidText for reading books and articles, Notes Plus for note taking. Both are a little more finicky than other options, but they each have unique features I find indispensable. (If you haven’t completed a handwritten problem set with lasso-and-drag and scribble-to-erase, you don’t know what you’re missing.)
I do most of my writing straight into Google Docs on the Apple keyboard cover. I also have a LaTeX app and a Jupyter console (Juno) that see some use when I’m away from home, but I still prefer to work on that stuff at a PC.
Edit: Oh, and outside of work, I use GarageBand with a Lightning stereo condenser mic to record music. I doubt if anyone with real production skills would enjoy it, but it works perfectly for my purposes.
My secondary use case is board games. Carcassonne and others have pretty good ports which was very handy for playing with people while traveling or instead of carting a bunch of boxes (or bags) over to friends' homes. Everyone but me has gotten married and had kids so gaming is much less frequent these days, and usually hosted by the guy who has the biggest board game collection when we do gather.
My final (present) use case is tabletop roleplaying games, but that's also covered by my current device. Hero Lab has an iPad port which was handy for some games I ran in the past, and hope to run again in the future.
Affinity designer is a great vector program. Lumafusion is good for editing, though I havem’t used it much. Ferrite is good for audio. Most areas have a few standout apps, depends what you want to do.
Explain everything is good for making educational videos.
Killer app is (a) ultra portability with genuinely all day battery and LTE for meetings and commute with (b) every tool an office user uses.
Some if us also code (servers and infra not desktop or mobile apps), works great for ‘Git Ops’ workflows.

I have a MacBook Pro as well now, so I hardly ever use the iPad Pro for that sort of thing anymore but it was a pretty good experience.
It’s also an excellent music creation device. I originally bought it so I could use apps like Korg Module and Gadget and it’s great for that purpose.
It’s also my favorite device for reading kindle textbooks.
I think I would like to move to using Adobe Lightroom on the iPad.
But it works well enough.
I am looking forward to the Steinberg Dorico team putting out a MusicXML viewer for iPad... and have also occasionally contemplated developing one myself, to make sure I get the feature set I want. :-)
[There are good PDF-based systems, but we sometimes need to switch keys for vocalists, and MusicXML works better for that, if you don't know in advance to prepare a new document.]
I've done iOS dev in the past (it's not my daytime gig at the moment), so if your contemplations ever get more serious and you want an enthusiastic partner, hit me up. I'd love to do something musical.
Other than Apple Notes(with Apple Pencil), and watching NetFlix, I dont make good use of it. I'd love to get some recommendation for useful apps to try...
