IMO bang for buck is to invest in: * reproducible fast dev environments - anyone should be able to build anything pretty easily fairly quickly * culture of design reviews, testing, and code reviews. * CI/CD, static analysis, PaaS, dependency management. You can do all of these without Google-level or really any bespoke tooling. A lot of what google builds is for operating at Google scale - distributed builds and running of huge applications - and even then this tooling this simply enables working at this scale, it comes with a lot of cost(speed/complexity) and jank you don't need at smaller software shops.
