Is Squid Needed If Using Unbound?

[ticker]

My network is basically a few VLANs (family VLAN, my vlan, guest vlan)
And I run Unbound on OPNsense. That acts as the DNS server, all devices point to it. (Which I do have a question, is this type of DNS considered an "Authoritative DNS Server?" The 2 confuse me still.

Anyways, I read about Squid, and how it can cache stuff and speed up things.
I am curious, my drive in my system is about 500gb. So OPNsense is using barely anything of it. Should I install Squid? Or does Unbound have these capabilities?
I see there are some settings about Caching in Unbound > Advance. Not sure if changing these numbers would be beneficial.

Not that stuff is slow, but more speed is always better lol ;)

Authoritative DNS servers host the data that contain the mappings in zone files. Resolving DNS servers need to consult an authoritative server if the mapping is not in their cache.

Squid is great for static websites and slow connections. With the move to interactive sites and high throughput broadband, it is less useful in making internet browsing faster and is more used to inspect traffic at the URL level and overcome routing issues.

Everything that sits between a server and a client and changes the packets, such as proxies and NAT in some way breaks the protocol. Direct connections always work best.
