I’ve got pretty much the same constraints: full time job, family of 5, etc.
I tried to do BunPro in the beginning but had to drop it by level 10. I just couldn’t apply the time to both.
However, I did get a lot out of the N5 lessons. I think that’s really all you need to get started and possibly some of the N4 stuff. What I do now is I’ll do the lessons on BP, but I won’t really bother much with the reviews. I’ll do a few when I can but it’s not priority so I’m ok with just letting them slide.
What helped me a lot more was passive learning through YouTube. Just watching Japanese Language videos interspersed with my regular YouTube watching during free time helped me immensely and better fit my schedule. I will note that I don’t watch any TV so all my screen time is YouTube anyway.
Here’s my basic list of channels that I would recommend:
Cure Dolly’s videos provide an amazingly intuitive way to think about Japanese. The content is quite good, but some people are turned off by the gimmick of the voice and having a CGI presenter. The titles are also a bit click-baity, but I honestly prefer her method over Tae Kim or any of the others I’ve seen.

SambonJuku 三本塾 does videos entirely in Japanese but he speaks clearly and is much easier to understand for a beginner. He’s a good teach and his videos provide a good way to watch/read if you turn on Japanese subtitles for the videos that have them.
Sambonjuku Beginner Videos - Very basic. A good foundation but you’ll quickly grow out of them.
Sambonjuku 日本語おもしろい Videos - Much more fun to watch, and more information. Watch with subtitles to supplement your WK.
Sarah K. is a professional translator and her breakdown of the pilot episode for the original Sailor Moon is a great resource for learning how Japanese in Anime is different from regular day-to-day conversation. She goes over the how different characters talk and a lot of the contractions and shorthand that they use.
