Just bought my first cold wallet (Ledger Nano S Plus). Any tips for a beginner?

As per the title. I have finally got myself a cold wallet and plan to move the majority of my bags straight onto it.

I DCA monthly with the occasional extra buy here and there. I've checked and Ledger support almost all of my tokens, had great reviews and seemed like the best choice for what I needed (cold simplicity). Also got 10% off in a Black Friday deal on the official site which was sweet.

I've heard the initial setup / operation can be a little confusing at first but I'm fairly tech-savvy so should be OK. I also love learning anything new like that so hopefully be an enjoyable experience.

Are there any cold wallet owners with nuggets of wisdom to share on setup, safekeeping, daily operation etc? I've read numerous things at different times but having some direct answers all in one place would be great.

As always any and all comments / opinions welcome. Thanks in advance.
