Which visa option is better for a family considering staying in Thailand: Digital Nomad or Muay Thai?

I'm trying to decide between the digital nomad option and the Soft Power option (Muay Thai). I have a wife and 2 kids (4 and under) that I hope can be dependents on my DTV. We do intend to stay in Thailand for most of the 5 years (while complying with the 180 day requirement) as we will be receiving financial support to do volunteer work.

I hope to try and get our application right the first time and thus I have concerns about both options:

Digital Nomad - I have solid proof of income from working as a mental health therapist with various firms but I will be working minimally with these firms if we were in Thailand because of our transition to volunteer work and time zone differences. If we did get approved for this option, would I have to show that I've earned income from these firms while re-entering Thailand on the DTV?

Muay Thai - I have no problem attending classes for years if we get approved for this option. My concern is whether my wife and kids will be approved as dependents since Im assuming most people pursuing this option are single men.

Any feedback/clarity you can give will be appreciated!
