If you have enough experience to make your own custom adventure for your players, I’d recommend that, so that you can easily adjust it to suit your players needs and preferences, as you go.

But if if you’re not comfortable with that, then probably just use the campaign that comes with the d&d starter pack (lost mines of phandelver or something like that).
It’s not an especially amazing campaign, but it has a decent mixture of dungeon crawling and roleplaying, and the story/encounters are simple enough for beginners to understand. It’s a safe bet to ease players into TTRPG.

You could also try a totally different system. I hear good things about Blades in the Dark. I’ve never played it, but what I hear sounds like it avoids overwhelming new players.
