I'm late to this review, but just an offer that this could be written more compactly/without duplication:

switch flag := flag.(type) {
case
    *cli.StringFlag,
    *cli.StringSliceFlag,
    *cli.BoolFlag,
    *cli.IntFlag,
    *cli.Int64Flag,
    *cli.Uint64Flag,
    *cli.Float64Flag,
    *cli.DurationFlag:
        flag.EnvVars = append(flag.EnvVars, envvar)
}
