ETF for longterm passive investing … iShares Core FTSE 100 UCITS ETF GBP (Dist) ISF?

iShares Core FTSE 100 UCITS ETF GBP (Dist) ISF – long term hold?

I’m looking for a fairly passive ETF that I can routinely put X% of my income into for the foreseeable future. This ETF also has a 4.45% dividend yield currently which is a massive benefit.

It’s done well to track the S&P500 since it’s inception and just wondered if anyone had any reasons why I should be apprehensive of this ETF or should be avoiding it completely?

Or whether anyone had any other ETF recommendations for a longterm passive strategy?

Thanks for all and any advice.
