Thanks, Rubic!

First, if you're planning to live here 8+ months per year, then the Golden Visa/Investment route isn't necessary.

While the low residency requirements of the golden visa are potentially attractive, I expect I would be moving permanently. I did not realize there was an 8+ months/year option and would love to hear more about that - does it have a path to permanent residency status?

Would you be retiring in Portugal or do you plan to continue to work/be employed whilst living here?

I expect I will be working about 5 more years - remote tech consulting, about 20 hours/week - then retirement. But I want to have the option to relocate by early next year, so a retirement visa would not be a good match.

A potentially odd thing about my case is that my two cats have to be able to relocate with me. I gather this is generally not an obstacle so long as they get health / vaxx certifications by the right vet. Although international plane travel is probably nightmarish for a cat. I actually looked at the possibility of taking them by sea, but it's either impossible or prohibitively expensive.
