Having difficulty finding tickets that specifically cover admission to both the Basilica/Church and the Medici Chapel on Get Your Guide and Viator. Does an admission ticket to Medici Chapel also get you into Basilica of San Lorenzo, if not, where do you find those tickets?
It's been pre-covid since I was in this church but then you had to walk thru the church to get to the Medici Chapel which is off to the back/side. Here's a link to the floor plan.

I looked quickly on the websites for both the Medici Chapel and Basilica San Lorenzo and don't see that they sell tickets ahead of time. When I went you just bought at the door. I did find this statement on the website:
"Il Biglietto si acquista direttamente in biglietteria"
translated: Tickets can be purchased directly at the ticket office
BTW, I would buy tickets directly from the sites not from 3rd parties like Get your Guide and Viator. Viator is owned by Trip Advisor and does not run tours, they are just a middleman. They also charge 20-25% to the guides and sites for whom they sell tickets.
I purchased the Firenze card which gets the user into both. Post COVID it could be different, but when we were there in October, a few years ago, there weren't lines at either. Also, if you look at the RS guide, I feel like he provides enough information that a guided tour is not necessary. If you'd like a guided tour, I'd book directly with the tour company, not Viator which sells other people's tours.
Medici Chapel has had lines outside it the last few times I've been there but nothing like other museums. (I stay at a nearby hotel usually)
So on this page of San Lorenzo's website (kindly provided by Pam) is a paragraph in a green bar that reads: "During its long history, the Laurentian Medici Complex was separated in its management into the complex of the Basilica, the Medici Library and the Medici Chapels" Below it is a sentence in Italian which translated reads, "For this reason, 3 separate tickets are required and observe different visiting times for the entire complex." Odd that they wouldn't have included it in English but there ya go: they are managed separately, have different visiting hours, and are ticketed separately.

Given the good info on the San Lorenzo website, I wouldn't book any sort of combo - for a premium price - through a 3rd party. Maybe pre-book your Cappelle Medici visit for a corresponding time the basilica is open and just buy a walk-up entry for the church. Download the S.L. brochure on the website for listing/location of the artworks/monuments throughout the church. I wouldn't purchase the Firenzecard just for this; you'd need to visit many other attractions to make good on the price. The basilica isn't as big a draw as the chapels (but worth seeing, IMHO) so there shouldn't be any sort of line.
Tickets for Cappelle Medici are on the official b-ticket site:
https://www.b-ticket.com/b-ticket/uffizi/default_eng.aspx.html
Note the CUMULATIVE BARGELLO ticket offered on b-ticket? It still doesn't cover San Lorenzo but if you intend to visit enough of the attractions it covers (Bargello Museum, Cappelle Medicee, Palazzo Davanzati, Orsanmichele e Casa Martelli) - and you are NOT going to the Uffizi and/or Accademia or are purchasing separate tickets for those - it may be a worthwhile purchase.
