I think there a few things that could help. One is to respond to recruiter emails, even if it is just to say "sorry not looking to change right now, would love to check back in a couple of months," even if its a company that you're not 100% sure you're interested in. If you have time, do an informational call to learn about culture / team / etc. Who knows, maybe you'll get excited enough to interview (item #2 in your list). Regardless of interest, I think once every 6 months or so it is a good idea to go through a full interview loop with at least one company. Interviewing is a skill that is largely unrelated to your day to day work, so this is probably the best way to practice. It also gives you a rough sense of what companies are paying (item #1) and what skills/technologies they are looking for (item #3).
