Out of all of those, I'd definitely recommend the Lost Stories for the First Doctor. Farewell Great Macedon may be narration style, but its still very evocative and feels very much like a '60's serial.
I just finished
Farewell, Great Macedon, and the story is quite good, and does indeed fit the style of season 1 perfectly. It seems the adaptation didn't try to reconcile it with the later series but kept the early assumption that the Doctor and Susan were from humanity's distant future, as well as some other oddities like the Doctor saying he'd pursued a medical degree. The companions' debate over whether history can be changed also sort of feels like "The Aztecs" never happened. Barbara's conviction that history can't be changed would fit in well after that, but Ian acts as though the issue has never come up before.
The narration style was not easy to get used to, especially with the weird practice of delivering so many characters' lines as paraphrases (e.g. "He would see them later, he said" rather than "'I'll see you later,' he said") yet nonetheless performing them in character. That's just bizarre and distracting. Russell's First Doctor was often pretty good, in delivery if not in timbre, but it was sometimes hard to tell his Doctor from his Ian. Ford was better at differentiating Barbara and Susan, and captured Jacqueline Hill's tones rather well.
It's a good work of drama, but its take on Alexander the Great is rather hagiographic and it takes a lot of liberties with history. I've been reviewing my old history texts and Wikipedia to put it in context. Apparently historians tended to see Alexander as a drunken thug and a tyrant until a historian named W.W. Tarn came along in the 1930s-40s and popularized a revisionist view that painted him as a virtual saint dedicated to the Brotherhood of Man. That was clearly the basis for ATG's portrayal here. Modern historiography tends to land somewhere between the two extremes.
They also compressed the timing a great deal. All three of Alexander's close friends who were murdered by the conspirators were real people who died more or less as depicted, but Cleitus was killed 5 years before Alexander, Hephaestion 8 months before, and Calanus several months before, none of them in Babylon. Also, there was a real theory that Antipater poisoned Alexander, but it's been largely discredited as an attempt to smear his descendants. The story also painted Iollas as a priest and co-conspirator of Antipater, but he was actually Antipater's son (which I guess would make him Anti) and Alexander's wine pourer.
Also, the story portrays Ptolemy as a "Nubian," along with an unfortunate Magical Negro portrayal of him as a loyal and stoic servant of Alexander, but the real Ptolemy Soter
looked more like Chief O'Brien.
If there's a documentary feature, I haven't listened to it yet. I hope they talk about the adaptation and how much was in the original story. If Ptolemy was originally written as black, that might've created some problems with Hartnell, unfortunately.
