I am not in the US and don't understand some of the abbreviations or terminology such as "common degree" that you've used, but I do have a background in higher education and as no one else has responded, I will chime in.
A couple of questions to clarify, both for me and perhaps for yourself.
Are you after a degree that is perceived as prestigious? Or is the content that you would learn from a less prestigious institution sufficient that you would still be gaining a lot of knowledge?
Are you wanting a degree so it adds credibility to you as a coach/owner? Or again, is it the knowledge and practical experience that perhaps might be more important. Perhaps again, a less intensive program might be very very useful whilst allowing you more time with your family and practical management and work experience?
Do you think people who might attend your future gym would really mind what academic qualifications you have? Would they check which institution they are from or even know which are more respected or not? Perhaps this is less important than you might think.
A good way of working out which institutions are preferred by potential employers is to call and ask them for recommendations. If you can find a job ad at a gym that looks like the sort of thing you would be interested in in the future, perhaps a HC type role, then call them and ask if they are looking for candidates with particular qualifications and if so, what qualifications and institutions do they prefer? Do they feel differently about online qualifications (ask if they check or differentiate)? Ask them for advice.
Good luck.
