Static file serving? Sure!
Load balanced proxying? mod_proxy_balancer is great!
Fine grained caching? mod_disk_cache is also great
Updating loadbalancer bits via the api?
mod_proxy_balancer supports a balancer-manager endpoint for that to do live updates
monitoring? mod_status + prometheus exporter or
mod_prometheus_status
native LE support? https://github.com/icing/mod_md is going to be rolled into upstream apache
That said, netcraft says Apache still runs almost 25% of the internet, which is no small stake: https://news.netcraft.com/archives/category/web-server-surve...
The weakness of nginx is that it can't have a dynamic module and if it's not compiled in, you need to roll your own build, which I won't do due to maintenance burden.
