This gets us to a nearly clean state across the toolchain. A couple of these are checks that I don't think we want to try to rigidly use and I've disabled them completely. Others I've added relevant `NOLINT` style suppressions or applied the automatic fix suggested by `clang-tidy`. The implicit conversions that are allowed here with `NOLINT` are probably worth at least a tiny bit of scrutiny to see if we could replace the construct with something more direct without undue effort and no longer need the implicit conversion. But until then, it seemed fine to suppress.
