Does Wikimedia use InnoDB, Maria or something

mediawiki-config (where most of

comes from) gives no indication that we override it, so AFAICT the
MediaWiki default in includes/DefaultSettings.php line 1541
$wgDBTableOptions = 'ENGINE=InnoDB';
applies.
WMF uses puppet to configure servers, so actual DB config settings come
from puppet manifests and roles, such as

Otoh, our db tables probably weren't created by the mw installer, so I feel
that $wgDBTableOptions probably doesn't have that much of an effect.

P.s. out of curiosity, which tables are "memory" tables?
It does, as most tables are created/updated via sql.php, which
handles the variable substitution.
As far as memory tables: hitcounter & profiling, neither of which is used.
