The T450s would probably benefit a lot from the existing support for
ThinkPads. But Broadwell really isn't a weekend port (Sandy or Ivy
Bridge would be for a ThinkPad) because we have few Broadwell ports
and an ugly blob situation.
Anyway, chances are close to 100% that the T450s has BootGuard in

You don't *have to* spend time cleaning the ME, you *can* spend time
with it. It is actually unknown if that lowers or highers security,
so there is really no reason to advice to do it (unless you need more
flash space for fancy stuff).

The G505s requires a lot of other blobs, IIRC: xHCI (optional), AtomBIOS
for GFX (which even runs in the OS on the host CPU), maybe more I don't
remember. I don't see how that is better (you seemed to want to sell
that by only stating absence of blobs, ignoring those it has instead).
