I don't like this approach - although I've used it on plenty of
floors. It works fine at first, but it shrinks over time and gaps
open up. If your gaps are small to begin with, then it might work for
you.

Screwfix offer a slightly flexible floorboard sealer in mastic gun
cartridges. I might use this sometime and see if it's any better.

- What glue would it be best to use?

Cheap PVA - go to the builder's merchant and buy a gallon for almost
nothing. It's also a perfectly usable wood glue. Don't let the frost
at it though.

I've found it's not as good as bespoke PVA wood glue, the set result is
far less flexible / more brittle; for those who remember it more like
Cascamite than bespoke PVA wood glue.
