Crem vs Church? Burial vs ashes?

3 funerals in the past month:

Ex-brother-in-law's (terminal) Dad, at the Crematorium, with a Vicar.

Old workmate's (terminal) wife - Crem - Vicar - wake after.

Ex-father-in-law. Church - graveyard - wake after.

I still haven't made up my mind what I want for me, when the time comes. At the graveyard on Tuesday, my kids and I visited a few graves of those we knew (young people) who have passed away - and left a rose on each. We also had a little conversation with the dear departed.
You can't do this with Those Who Have Been Cremated.

I'm not sure whether I want people visiting me after I've been buried, but I don't want to be forgotten either.
