While it fails some of the original requirements, the Giant TCR SLR is worth a very serious look. They are rare to find with an OD2 full carbon fork (usually only in international [Asia] markets)... but if you can find one, few aluminum bikes will rival this one, and you're unlikely to ever see another OD2 version in Europe or the U.S. I have the pre-internal cable routing version, which I sourced in Taiwan, and it is an impressive bike in all respects, including the fact that it is strikingly comfortable to ride.

An interesting fact regarding the stiffness is that the year I bought mine (2013 maybe), Giant published the stiffness number of their frames... The regular OD (not the OD2 version) nearly rivaled the TCR Advanced SL in head tube stiffness and exceeded the TCR Advanced SL in BB stiffness. Not surprisingly, Giant never publicized the OD2 version of the SLR frame stiffness vs. their flagship Advanced SL... Sadly, this frame has all-but disappeared from the Giant line-up in favor of carbon, making it somewhat of a unicorn in the world of aluminum frames.

With 40mm carbon tubulars, SRAM Force and no exotic components, I have mine at 6.69kg.

Other aluminum bikes I've owned or own include: Kinesis Racelight Aithien (solid, but choose the seatpost wisely... not compliant), Velocite Selene (unpleasant to ride), Prolight Carrara (smooth ride, but heavy), Kinesis Racelight T3 (has much in common with a boat anchor)

The Ridley Helium Sla is really a great frame. I have a size medium built with Ultegra/DuraAce and Caden clinchers, which come in at 6,95 kg complete. It is super fast and really stiff and is just a blast to ride. I also have a carbon Fenix SL at about twice the price but the Helium is still my favorite for my typical riding.

The Helium is made for BSA bb and standard 27,2mm seatpost, so nothing weird proprietary to cater for. The hydroformed tubing doesn't show on pictures, but except for the seatpost all tubes have been shaped and tweaked, which I think looks smashing.

If we exclude the "sponsoring pros in grand tours" how about something from Vynl Bikes. They tick all the other boxes, simple design, threaded BB, race geometry. Perfect if you want to run a mechical group. Heck, they even sponsor the Clif Bar Racing team that rides the USA Crits series, so they are race worthy. And the head welder Frank Wadelton has been building lightweight alloy frames for a LONG time, and has probably welded more alloy bike frames than anyone else in the industry.

specialized allez sprint.

I was going to say ‘no way this has a pressfit BB’ but then saw this was in fact a BSA BB.

Something a bit hard to find - 2016/17 Bianchi Freccia Celeste.
Ticks all of your boxes, 1.2kg frame and full external routing. The only drawback I can think of is it's a straight through 1 1/8" steerer.

Where do you see that? I always thought it had bb30?

The current Standert Kreissäge is T47. The original model used PF30.

De Rosa Team? 31.6 seatpost though.
