Moving to seattle

Hi all, I'll be moving back to the pnw soon, seattle specifically now, and had a couple questions.

It's looking like I'll be in the Wallingford area, can anyone give me some insights, cool spots, ect around there? Trying to be a healthier guy so i plan on walking around and exploring a bit on foot so any suggestion is appreciated! I'm early 30s and mostly a homebody, not a big drinker/party type

Also, ive read on here how the public transit is great if you're in seattle proper, which i assume is over the bridge. I would figure I'm not too far up and there seems to be a few stops around where I'd be so im just curious if being north of the bridge will be an issue with no car. Big draw to the city for me is the public transportation as someone who has some medical issues and driving can be a challenge.

Thank you for any answers!
