Apologies for the late reply!
I realised I had missed a few errors in my apache restart log. Even though
the final message I received was "httpd restarted successfully.", some
errors like the "(13)Permission denied" one were being reported as well (I
just didn't scroll up far enough to notice them). Oddly enough, these
errors didn't always show up in the actual error_log file.
So I restarted from scratch again, following the same steps as outlined in
my opening post, but using a conda environment (djangotest), conda
virtualenv (djangoenv) and non-conda (base python) virtualenv.

Adding ` socket-user=#1000` DOES result in a successfull apache restart
without any errors in the output. However, the apache error log then reads:
Current thread 0x00007f8ed2d49880 (most recent call first):

I wanted to add a new LoadFile statement, but it seems that the mod_wsgi
version, installed via pip in a non-conda virtualenv (base python3.6) was
still associated with conda somehow:
ldd django-base-env/lib/python3.6/site-packages/mod_wsgi/server/mod_wsgi-
py36.cpython-36m-x86_64-linux-gnu.so
linux-vdso.so.1 => (0x00007ffeeefda000)
libpython3.6m.so.1.0 => /opt/miniconda3/lib/libpython3.6m.so.1.0 (
0x00007f3813c24000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f38139fa000)
libc.so.6 => /lib64/libc.so.6 (0x00007f381362d000)
libdl.so.2 => /lib64/libdl.so.2 (0x00007f3813429000)
libutil.so.1 => /lib64/libutil.so.1 (0x00007f3813225000)
librt.so.1 => /lib64/librt.so.1 (0x00007f381301d000)
libm.so.6 => /lib64/libm.so.6 (0x00007f3812d1b000)
/lib64/ld-linux-x86-64.so.2 (0x00007f38143a6000)
The weird thing is that I explicitly used the base python3.6 and its pip
binaries to create this environment.
/usr/local/bin/virtualenv -p /usr/bin/python3.6 django-base-env
I suspect this is caused by the fact that the original 3.6 install wasn't
configured with the shared_library option and that it is somehow defaulting
back to conda's shared library?
Adding the original LoadFile statement (using the /opt/miniconda path)
doesn't change the apache error log.
In all cases, `httpd -M` shows Loaded Modules: wsgi_module (shared)
Perhaps I should try installing a second python 3.6 (non-conda) version?
Although I'm a bit afraid I'll mess up my system if I'm not careful. I
actually tried removing this python3.6 version using yum, but that didn't
remove the actual binaries/symlinkms/paths apparently.
