Thanks for the tag @MiaSrebrnjak 
Welcome to HubSpot, and the HubSpot Community, @MDeMarco! As @Jnix284 mentioned, if you have an onboarding specialist helping you, definitely work with them.
As for other tips, I’d spend time in HubSpot Academy. The courses for Marketing Software, Sales Hub Software, and Inbound are all great.
I’d encourage you to stay active in Community, too. Set aside a little time each week to look through current questions and their answers. It’s one way I learn new things in HubSpot after 12 years around this corner of the multiverse.
Happy HubSpotting, friend!
