Congrats on the windfall, Jeffra! The Board Game Geek Top 50 list is a good place to start. From the list I would say Wingspan, Root, and Catan are all must-haves.
A few that aren't on the list but which I would consider necessities include Uno, Ticket to Ride, Villainous, Apples to Apples, and some really basic stuff like checkers, chess, and/or go sets.
Twilight Imperium and Betrayal at House on the Hill are the two most played games our board game club uses- but those games are kind of elaborate, which is what the club likes, so they might not be the best selections for a general audience. It depends on what your collecting focus is.
For D&D- get the Starter Set and the Core Rules Set and then monitor to see whether the popularity warrants additional purchasing in the future. Between those two sets, you've got the essentials.
You can also see a bunch of other librarian game recommendations on the GameRT Blog - look for the monthly "GameRT Recommends" feature.
