With this config, all requests to "/client_data<anything>" will be
routed to "http://web:5000/client_data" URI.

When using variables in the proxy_pass, you are expected to
specify _full_ URI. Using an URI component to replace a part of
the URI matched by location prefix, won't work. See details in
the proxy_pass directive description,
http://nginx.org/r/proxy_pass.

And this config is quite different. With this config, requests to
"/client_data<something>" will be routed to
"http://web:5000/client_data<something>".

In both cases, "/client_data" part in the proxy_pass directive
looks unneeded. That is, use

proxy_pass http://web:5000;

instead. And with variables equivalent construction would be

set $upstream_client_data web:5000;
proxy_pass http://$upstream_client_data;

Note no URI compontent in proxy_pass in both cases.
