I've borrowed a friend's DJI in the past for scouting fields but I was taken back by the price of admission but now I see DJI has come out with a Mavic Mini that uses a cell phone in conjunction with the controller (download the App) for under 500 bucks complete with extra batteries, props and hard case.
I've had a DJI drone for a couple of years. My thoughts:
Buy whichever you feel financially comfortable with crashing or losing in a remote place - but that said, I've had a couple of prangs with mine and been amazed by the robustness of it. Parts are easily available (not necessarily cheap). It's a beautifully engineered machine.
If you are going to use maps at all, you can only get whatever brand the drone manufacturer lets you use. Unless you buy some other aftermarket app. DJI switched from Google Maps to Here Maps about 6 months after I bought mine, and the Here Maps were an absolute dog - low resolution and out of date. I had no choice, they just decided and did it. Occasionally I can still get Google Maps but it's not easy. I don't know if DJI still uses Here, but it can make a big difference if you rely on them.
Your 1/4" drive socket set won't be much help for repairs. If you don't already have them, you'll need a set of tiny screwdrivers of different types, tweezers, magnifier light and other kit for repairs.
Make sure your phone has a good bright display in daylight. Mine could be better, so I fly it from a spot in the shade so I can see the screen clearly.
Don't do firmware or software upgrades unless you need them to fix a problem that's bothering you. Reason: the upgrades can introduce new problems and new limitations imposed by the manufacturer.
Keep each upgrade as an app in case you want to roll back to the previous version and the manufacturer has taken it off their website. Sometimes you can find old versions on other sites, but they aren't necessarily safe.
Keep an eye on the users forum/s - they can save you a lot of time/grief and be really helpful.
Drones have similar limitations as helicopters... look up vortex effect before you fly close to walls
(One of my crashes)... the other lesson from that is that if you are practising precision flying close to stuff, the lower you have the machine, the less distance it falls when you hit something...)
It is modern technology at its best, or worst, so don't assume you are the only one who has access to your pictures and track.
Fly it lots, keep current, and have lots of fun (I've sort of lost interest in mine but occasionally haul it out to get aerial photos, and I practically have to relearn how to fly it).
It's great to learn a new skill, and having bought one, as another poster said, you'll be in a great position to know better what you want if you need to upgrade.
