I use "Other" most of the time anyway.
I used to try to remember labeling all of my Garmin-recorded workouts on Garmin Connect, but I never really sat down and tried to analyze them later -- time spent in each HR zone, speed on gradients, performance vs. weather, or whatever. I just didn't care. I'm not gunning for shaving minutes off my triathlon times (maybe because I don't do triathlons), I didn't spend another grand on a power meter for my bike, I'm not trying to "meet my macros".
Obsess if you want, but don't get upset if you don't end up with a medal around your neck (and I'm not talking about so-called "participant medals" that you get for just showing up).
