Baby led weening

My son is 4 months old so I have a little more time before we start anything other than breastmilk. I keep reading about baby led weening and I think we're going to try that once the time comes. I'm doing research daily about the DOs and DONTs but I wanted to see if any mom's here have tried it. What were/are your favorite foods to give baby? Suggestions for first foods? Has anyone tried and it not worked so you have to go to purees? Any advice/stories work! Thanks in advance!
