Actively Managed ETFs and Taxes

I am very interested in some ETFs that are actively managed, so can trigger tax constantly even if never sold a share. I have zero experience with it, and my search tells it is better in a Roth IRA. But I may have to put some of them in a taxable account.

What I want to know is, for those that have active ETFs and they are in regular brokerage accounts, anything I need to know that you learned with experience? Thanks for your time!
