You might want to peek at https://github.com/headwaymaps/headway . I have never used it myself, but it at least shows how to integrate the different pieces.
The individual software components often have alternative with a similar scope. So if you don't like a choice headwaymaps made, browse around.
The data sources are mostly "unique", i.e. everybody downloads from the pages (Geofabrik, Who's On First, etc), so not much to gain here.
Editing styles has some alternatives, but the OpenSource editors are far away from the quality of the Mapbox editor. Maputnik or editing the 1000+ SLOC JSON by hand are the way to go, imo.
Personally I use GeoFabrik to download OSM extracts → osmconvert to extract the smaller bounding box I am interested in → tilemaker to render vector tiles to individual .pbf files I can serve like it's 1999. The bounding box extract is not necessary, but it's much faster if you need to tweak things in tilemaker. Both tilemaker and osmconvert are packaged for at least Debian out of the box, so setup is easy enough. Rendering a decently sized metro area takes < 30mins with this from scratch of compute, < 5min with the bounding box extract.
Note that adding icons (sprites) or fonts is extra work that comes on top. And while the tools themselves are great, there's still a lot of gluing/plumbing/fitting things together that you'll need to do. If headwaymaps works for you, it's probably the easiest choice.
If you try to open a host from that list in IE11, it will open in Edge instead. The process really is just sending them an email, so I did it for my personal site which still received occasional IE11 traffic from "yesteryear's megacorp" IP ranges. I don't have enough IE11 traffic to judge if it worked for these poor users, though it does on my Windows PC. Given my effort was literally sending a single email and wait a month, I am happy even if it helps only a few people.
