When the host is far away, it makes sense to use hop-by-hop choke packets to resolve congestion. But is there situations where normal choke packet is more appropriate?

And by the 'source' we mean a sending router correct? If so, how does the PC connected to the source router react to choke packets?

"Choke packets" haven't been a thing for some time.

ICMP source quench packets were deprecated in 1995 by RFC 1812, some 27 years ago. Source quench packets were originally intended to be sent by an in-path router, but could also be sent by the end host.
