I had absolutely zero interest in teaching new divers by spending my weekends in 8 ft deep chlorinated swimming pools, but went down the divemaster path to improve my diving survival skills to take care of myself and my wife in the water. Being a DM was never on my radar until we went on a dive vacation to Fiji and had a terribly frightening experience with an awful dive operator. A couple of the guys on the trip were both PADI pros (one instructor, one AI and one DM), as well as being GUE trained divers, so I spent a lot of time talking to them toward the end of the trip when I realized I couldn't count on poor dive operators for my (or my wife's) safety. I was torn between the fundies training path and the DM path, and ultimately did the DM certification (still haven't gotten around to taking Fundies)
I had no intention of working with OW students, but set a goal of completing the DM certification. What I did get out of the program was a much better appreciation of what divers around me are doing and how well they are doing it, much better dive judgement and ability to assess what's going on, and much better above and under water diving situational awareness. Plus a lot of new and improved skills, more diving opportunities, lots more friends from diving, and more confidence in the water. Plus sometimes good pro discounts on gear and trips and opportunities to participate in pro-only events like DEMA
All the usual advice applies - find the best instructor you can for the DM program, take it seriously and put at least 100% effort into it, including the things maybe you don't view as important like interning for an OW class and going through a Discover Scuba Diving session, and all the rest. There are definitely skills that transfer over and help if you're going to take Fundies, like the whole range of knowledge from going through the Encyclopedia of Recreational Diving, dive planning practices, and situational awareness of what divers around you are doing, where they are, and the problems they might be experiencing
What you won't get from the DM program is learning how to dive with a long hose on your regulator, do backward kicks or perform valve drills, unless your DM instructor helps you with those when you ask. You should figure out what skills are most needed for the diving you intend to do and start there
