Taking photos.....100%
I used to print pictures and put them into photo albums. When the kids were in school, pictures were asked for in certain projects/Communion, Holidays, etc. When each one got married, the photographer and videographer (is that a word?) asked for pictures of each growing up/family, etc. The clip put together would be shown at the ceremony. I would print pictures and delete from my iPhone not to have a ton when I finally got a smartphone. The albums were great to look back on, memories, etc.
Today hardly anyone prints anymore. Even if no one asks for pictures, great to take. For our selves, our kids, grandkids. t brings up so many wonderful memories of our past. My daughter twice recently has asked me if I had any pictures of her cheerleading days and just the other day - pictures of our 11 night DCL Med cruise. (for school/she is a teacher's assistant).
So, yes. Take plenty of pictures and videos.
