I'm with Joy. Most customers only care about a couple things... leads and revenue. Everything else is too in the weeds and over their heads. Unless you're dealing with a marketing director that is also on the same level knowledge-wise, it's basically a waste of time to create in-depth reports. Boil it all down to how did our work affect your business, and then figure out how else you can help - e.g., re-engage lost opportunities, build a customer retention/loyalty program, gather reviews, use paid acquisition to increase lead flow, etc...
Basically the stats we use in Data Studio dashboards or GA are more internal facing. We come prepared with the data to share and support our campaign direction, but it's usually not worth reviewing a ton of data.
Just an opinion from what I've seen, because I used to build out reports on customer facing folders/subdomains, send reporting, and build custom Data Studio dashboards. We still use Data Studio, but clients never really care about looking at the data... and they never do on their own time either unless it's tied to leads/revenue.
