In a similar position, I don't write much code anymore, but I review a lot.
I don't do the 'you should have made this const' or 'this variable is badly named' type of review... But I do a higher level check that nobody is overcomplicating simple things and building 37 new microservices when they ought to just be using one that already exists.
Overcomplicating simple things is a really common way to justify growing your team, getting a promotion, etc.
Suddenly the 'internal printer management team' needs 8 developers, dedicated
network bandwidth, and a project roadmap multiple years out with shiny webUI's, when all we really needed was a couple of dumb printers and 0.1 people to manage them.
