QOS recommendations to combat bufferbloat

Question

I have a network at home with 3 VLANS and wired into an Atom based appliance running Sophos XG Home. The traffic on the network is a mixture of IOT, Windows 10, Server 2022 and such. Netflix, Amazon Prime, etc. for family internet usage. 
 Connection is Virgin 100/10 cable connection, are there general QOS recommendations for applying against rules etc? Bufferbloat is a problem on the connection, but traffic shaping rules haven't been enabled as of yet. 
 Speed isn't the issue, it's latency..

There's isn't a lot to configure unless you want to do web category or application based QoS. 
 In general you can either create a User/Group or Network QoS policy, It depends if you have authenticated/clientess users or not in your home network. 
 For your setup, I recommend you to create three policies, one for IoT, another for the servers and a last one for family/general usage. 
 On the basics: 
 
 Always use the "Shared" option at bandwidth usage type. (For home usage.) 
 Remember to set the priority correctly on each rule. 
 Set the Upload/Download limits separately since you don't have a symmetric connection. 
 Be aware It uses KB/s (Kilobytes per second) 
 
 For the priorities you can use (0) for the family internet usage, (1) for the servers and (2) for the IoT stuff. 
 This should be enough to help with bufferbloat, here's a test I've made with my laptop over WiFi: (Using the Firewall QoS.)
