There are options, it depends a touch on skill level or technical friends. You could add a cheap USB card (if you can) to the computer and migrate or backup data. Alternatively, remove the HD and use an external USB Case or equivalent
If the networking works, there is a migration utility that Apple has you can install that will let you move data from one computer to a new Mac and perhaps some settings.. You can chose what to migrate, if you have a lot of data, you may wind up migrating some items and restoring some to another drive possibly.
I know some people really like Windows, and it can be cheaper in some cases., however working with it routinely for work, I find it cumbersome, the constant constant constant, (did I say constant?) patching, some of which has caused people problems, or small ones. Then even if you patch routinely you may still wind up with some malware or worse that will really ruin your day. Course, you may never see a problem.
The Mac is far more secure in this regard, and while you still need some vigilance in watching for security issues, its not nearly as problematic as it has been on Windows. Mac's have a tendency (IMHO) to last far longer than their Windows counterparts, I know people using 7. 8. 9. 10 year old Mac's routinely and some may have only recently not been able to install the latest version of Mac OS.. Mac OS updates are "Free".
If you come from Windows, there is of course a learning curve, however, there are plenty of places that cover Mac basics in videos you could probably watch on YT. If you're going to use it to edit your drone videos, iMovie (included on every Mac) will do a reasonably good job, if you have a need for more, there is Final Cut Pro, not cheap, but pro software rarely is. iPhoto (also included..) will let you manage all the drone photos you'll take easily. You can add third party editors such as Luminar to enhance the editing tools already in iPhoto,
