Even if you don’t want to cave dive, taking a cavern or intro to cave course will have a very good impact on your diving.
Yes, you might be right on that front. The reason I took the IANTD Recreational Essentials course was with the idea that I might have go partially down that route to get the training even if Caves were not my cup of tea.
I probably need to figure out how to do it without going to Mexico. The shop that I did it in Playa Del Carmen seemed focused on making sure I got the skills than letting me pass, which I think is the right philosophy. It just was a harder proposition to logistically arrange when I was on vacation and didn't know how long I would be there.
Easier if it was local. I only know of the GUE fundamentals course being taught locally (I live in the Bay Area) though. I am not yet clear if I am ready for that.
Are you interested in eventually doing deeper ocean dives to see the critters aka going tech or do you want to stay within recreational limits?
Yes, I think I'd like to go deeper, assuming that there are critters to be found! I have read stories about people who go deep diving for the sake of it, and that doesn't sound like my alley though.
I find the idea of blackwater diving absolutely fascinating for e.g. but I think I would rather first be a good diver before adding in another variable, cameras into the mix.
TDI cavern can be done single tank with some tweaks to your gear (adding a long hose, for example). So if you’re not interested in doing tech at all, do Advanced, get some dives under your belt, and go do cavern.
So the good news is that my coworker's philosophy towards diving was something I picked up on early on -- I use a backplate/wing, with one backup regulator attached to my neck and a long hose that I use as a primary. At least, I believe that in theory I have most of the gear in a single tank configuration that is "DIR approved".
I do have one clarifying question here: You mention TDI who I am not familiar with. Is my intuition correct that for technical diving, the certifying agency matters less than the instructor? As in TDI/IANTD (or even GUE?) all probably have some level of equivalencies and your instructor matters more?
