I rather mean huge amount of conflicting paths in 'x' and 'y'
subdirectories of my working tree after a merge, plus a few conflicting
paths elsewhere.

Almost. I mean to apply 'ours' option to the default 'recursive' policy for
all the files that reside in the directory 'x' of my working tree and
all its subdirectories (i.e., all the paths 'x/*')

No. I mean to apply '-X ours' to everything under 'x/', and '-X theirs'
to everything under 'y/'. Avoiding to repeat anything is the intention.

No, I expect no conflicts left in either 'x/' or 'y/' after "re-merge",
as neither 'theirs' or 'ours' should leave anything unresolved, and all
the other conflicting paths (left from original merge elsewhere) I mean
to resolve manually.

All the 'x/*' paths need 'ours', and all the 'y/*' paths need 'theirs'.

There are a lot of files under 'x/' and a lot of them under 'y/'. My
intention is to automate a lot of manual labor, and I'm not aware of a
mergetool that provides either '-X ours' or '-X theirs' resolution
automatically for all the paths specified.
