Lets ignore for the moment that wordpress actually doesn't have the
recommends line which is the TOPIC OF THE THREAD, but has instead a
"Depends: apache2 | httpd" among other things (← hint hint):
$ apt install wordpress nginx -so Debug::pkgDepCache::Marker=1
[…]
MarkInstall nginx:amd64 < none -> 1.16.1-3 @un puN Ib > FU=1
[…]
MarkInstall wordpress:amd64 < none -> 5.4+dfsg1-1 @un puN Ib > FU=1
MarkInstall libapache2-mod-php:amd64 < none -> 2:7.4+75 @un uN Ib > FU=0
MarkInstall libapache2-mod-php7.4:amd64 < none -> 7.4.3-4 @un uN Ib > FU=0
[…]

So, the reason you get apache2 installed is the second(!) dependency:
"libapache2-mod-php | libapache2-mod-php5 | php | php5" which isn't THAT
surprising or very hard to find, is it?
I would hence ask you to explain a bit better why you think APT is wrong
and provide an example which actually shows these characteristics.
Otherwise I will apparently be a tiny bit annoyed by this thread.

P.S.: For these cases -o Debug::pkgDepCache::AutoInstall=1 shows pretty much
the same with less scary details. I just picked Marker as it is literally the
first think I try and as I implemented the display of these "@un puN Ib" flags
they are a little less scary for me.
