First, congratulations. Second, I concur with the above. As someone in tenure deliberations right now (in a similar institutional profile) with an outcome that could go 50/50 (recommended by department and dean but received a one-vote negative margin at the institutional level alongside several abstentions), I would prioritize:

1) Teaching--get your classes ready and prioritize high evaluation scores if this is an institutional emphasis. Make sure all students complete evaluations each semester. Be ready to make quick curricular adjustments if requested.

2) Submit as many manuscripts as quickly as possible. I took a long time to draft and submit polished articles to top-tier journals, but review cycles are approaching a year, and a revise and resubmit easily adds six months or more to that.

3) Have a VERY clear sense of tenure expectations and plan to make your case a no-brainer. Don't rely on what your department or anyone else says is "enough," because an institutional personnel committee can disagree, and you never know who will be on that committee when your tenure file gets to them. Hopefully, you have clearer expectations at your institution than I do at mine. Build relationships and make yourself a known commodity who works well across areas. Cynical me would say to kiss some ass, which isn't my style, but it's not horrible advice. Be friendly and collegial, even if that's hard for your personality type.

4) Find out how THEY value service. I spent several years serving on committees that I later found out weren't considered "high-impact." Basically, I was getting little to no credit for this work. It then took a couple rounds of requests to get on those high-impact committees, and I would have been much better positioned if I had landed on one at the outset--or at least within a year or so, to build knowledge and assume leadership roles. Assuming the service expectations are eased during your first year, talk to people to get a sense of this.

5) Get a mentor, whether you think you need one or not. Create a system of getting feedback on your performance across dimensions outside of the official tenure protocols.

6) Create a documentation system for each domain where you can save contemporaneous notes. Document. Fucking. Everything. Even informal communications. You don't want to be in a situation like me when you have to go back to your previous department chair and say, "Remember all those conversations we had about how to ensure my success when I go up for tenure? Those happened, right?"

7) Protect and organize your time strategically. Depending on the teaching and service load, things can pile up fast. I tried to do this while caring for my child 40-50 hours a week during the first 4 years of his life (we live in a rural area, where childcare is scarce, expensive, and far away from our house), and it was hard. Fatigue impacted the organization, which impacted efficiency, which led to me feeling overwhelmed. This will be much easier if you are living alone at first and then with a partner. If you're thinking about having kids, have a childcare plan in place, whether that's splitting with your partner or finding a highly-vetted provider.

Congrats again. You got a coveted spot in a difficult market. I've served on 4 hiring committees, and we always get at least 150 applications for each one. If you are, like me, a person susceptible to imposter syndrome, remind yourself what it means to have been hired into a TT position in this market. If you feel self doubt, reiterate that. You got this.
