htaccess skip all following rules for subdomain match - apache

Question

I'm having problems with this answer https://stackoverflow.com/a/16800319/1283556
My current HTACCESS 301 redirects example.com to https://www.example.com, adding www. and https:// in as few redirects as possible.
I don't want it to add www. or https:// if the subdomain is m.example.com so I thought matching this condition and putting no rule, and using the [L] flag to stop doing future conditions would work.
RewriteEngine On
# Skip forcing www or https if the 'm' subdomain is being used for mobile
RewriteCond %{HTTP_HOST} ^m\. [NC]
RewriteRule - [L]
# Force www. and HTTPS
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI} [NE,R=301,L]
# Force HTTPS (www. was already there)
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]
# Don't remap resources to the index processor, just add SSL
RewriteCond %{REQUEST_FILENAME} ^.*^.ico$$ [OR]
RewriteCond %{REQUEST_FILENAME} ^.*^.css$$ [OR]
RewriteCond %{REQUEST_FILENAME} ^.*^.js$$ [OR]
RewriteCond %{REQUEST_FILENAME} ^.*^.gif$$ [OR]
RewriteCond %{REQUEST_FILENAME} ^.*^.png$$ [OR]
RewriteCond %{REQUEST_FILENAME} ^.*^.jpg$$ [OR]
RewriteCond %{REQUEST_FILENAME} ^.*^.jpeg$$ [OR]
RewriteCond %{REQUEST_FILENAME} ^.*^.xml$$ [OR]
RewriteCond %{REQUEST_FILENAME} ^.*^.txt$$
RewriteRule ^(.*)$ https://$1 [R=301,L]
# Remap /page/filter/?query to /index.php?page=page&filter=filter&query
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^/?([^/]+)/*([a-zA-Z0-9-]*)/?$ /index.php?page=$1&filter=$2 [QSA]
The effect of the above is:
example.com »301» https://www.example.com
m.example.com »301» https://www.m.example.com
The desired effect is:
example.com »301» https://www.example.com
m.example.com (do nothing, just serve content from example.com/mobile)
Server Version: Apache/2.4.10 (Unix) OpenSSL/1.0.1e-fips mod_bwlimited/1.4 Apache
It's worth noting that I got this working as a solution but I consider it a work-around and not a linear solution:
RewriteEngine On
# Force www. and HTTPS
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTP_HOST} !^m\. [NC]
RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI} [NE,R=301,L]
# Force HTTPS (www. was already there)
RewriteCond %{HTTP_HOST} !^m\. [NC]
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]
# Don't remap resources to the index processor, just add SSL
RewriteCond %{REQUEST_FILENAME} ^.*^.ico$$ [OR]
RewriteCond %{REQUEST_FILENAME} ^.*^.css$$ [OR]
RewriteCond %{REQUEST_FILENAME} ^.*^.js$$ [OR]
RewriteCond %{REQUEST_FILENAME} ^.*^.gif$$ [OR]
RewriteCond %{REQUEST_FILENAME} ^.*^.png$$ [OR]
RewriteCond %{REQUEST_FILENAME} ^.*^.jpg$$ [OR]
RewriteCond %{REQUEST_FILENAME} ^.*^.jpeg$$ [OR]
RewriteCond %{REQUEST_FILENAME} ^.*^.xml$$ [OR]
RewriteCond %{REQUEST_FILENAME} ^.*^.txt$$
RewriteRule ^(.*)$ https://$1 [R=301,L]
# Remap /page/filter/?query to /index.php?page=page&filter=filter&query
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^/?([^/]+)/*([a-zA-Z0-9-]*)/?$ /index.php?page=$1&filter=$2 [QSA]

Your original and updated question has two 301 redirect rules that are not good for both SEO rankings or user experience.
You can combine both rules i.e. http -> https and force-www into one and also take care of excluding m. host in the same rule:
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\. [NC,OR]
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^(?!m\.)(?:www\.)?(.+)$ [NC]
RewriteRule ^ https://www.%1%{REQUEST_URI} [R=301,L,NE]
Make sure to keep this rule as very first rule and test it after completely clearing your browser cache.
