Will you want to work part-time to have more income on the weekends even if you have a full-time job?

If you still have personal time to rest & relax - yes.

If that part-time work is an one-off gig and allows me to experience life in another way, then why not? I won't just look at money per say because the job must be interesting enough to warrant time taken away from the family.

To illustrate, pre-COVID, I worked before as a Japanese-English interpreter for travel fair, food fair, sake tasting event. Fun and interesting!
