Tailscale would be the most “secure” as you have no ports open and only you can access it. Keep in mind your services will only be accessible by you along as all your devices connect to your tailscale instance. Sharing access is possible but will require some explanation.
Wireguard is another option, just as secure as the first option, it will need one port open but the port only responds if you are connecting with proper keys/authentication. Like tailscale you can only access your services if connected to your wireguard instance.
Reverse Proxy, any version you choose will work, it depends on your preference of layout and user interface. Nginx proxy manager, haproxy, traefik. Each accomplish the same with different levels of setup, I listed them in my ease of use. If you use pfsense as your router haproxy installation is easy and there are plenty of guides about setup. Nginx proxy manager you can also find a bunch of setup videos where it’s running on home assistant.
With a reverse proxy you will open port 443 and in your firewall rules point it at your reverse proxy. Your proxy will then direct traffic to any one of your services. You will need a domain name so you can access service1.mydomain.com or service2.mydomain.com from anywhere on the web.
With a reverse proxy and any public website I recommend to run them behind a ddns like CloudFlare. You can do this for free and it helps protect your services against DDoS, bots/crawlers, and it obscures your HomeLab IP, as all incoming traffic goes through CloudFlare and then get directed to your HomeLab.
Additional security that can be implemented within your firewall is to block all traffic not originating from your country, or even only allow specific IP addresses.
I use a combination of all this above where a few services run publicly accessible, and everything else is accessed through tailscale or wireguard. Internally I run haproxy on pfsense where public service are proxied.
I also run nginx proxy manager for my local services, this allows me to access my local services such as service1.local.mydomain.com with a full SSL certificate. So once I connect to my home network with tailscale/wireguard I can type in these domain names into my browser. At some point I will move these into haproxy with its own frontend for internal services.
