Looking for advice on Account-Based Marketing tactics. What has worked for you?

I'm looking for some advice on running ABM motions, specifically the tactics themselves. I've looked around Reddit and the majority of people say the same things (ie use this tool, score the accounts, use intent, etc.)

I'm more interested in exactly what has worked for you as a marketing motion. For example, if you've used LinkedIn ads, how did you build the audience for targeting? Did you upload a company list and target ~20+ accounts at once? Or one specific company in a company list?

If you ran programmatic, how did you set this up? If you ran email touchpoints, did you send email to everyone or just the CXOs?

A lot of my experience is more in B2C, so any tactics that have worked well for you on ABM motions would be much appreciated!
