I think I posted on this before somewhere and somewhen, but when it comes to Germany, you immediately hit the problem that before 1871 the 'Leaders' of Germany were either leaders of only part of Germany, or Holy Roman Emperors, so the choices all come with some potential 'baggage'.
But there are still some Non-HRE - or "In Addition To HRE" German rulers available:
Otto the Great (Otto der Große). He was HRE for 11 years, but he was King of the Germans for 37 years, and his emphasis during both careers was to unify all the various German duchies, tribes, kingdoms, etc into a single entity (under himself, of course). Also beat back the Magyars at Lechfeld, one of those decisive battles that almost no one has ever heard of, and even has his own architectural style ("Ottonian") and presided over a 'mini-renaissance' fueled by emphasis on scriptorian literacy an cathedral schools and elite convents led by Royal women.
Frederick William, Elector of Brandenburg (Friedrich Wilhelm). If you want to pass on Fred the Great (Friedrich Wilhelm der Große), then you can't do better than The Great Elector (der Große Kurfürst). He's thd one who started the tradition of excellence in the Prussian Army, beginnings of Auftragstaktik, religious tolerance (welcomed Catholics, Jews, and a mass of Huguenot refugees from France), canal-building and infrastructure improvements, founded universities and libraries.
Ludwig II (Ludwig Otto Friedrich Wilhelm - there, that's almost all the German rulers' names in one!) King of Bavaria, called the "Swan King" (Märchenkönig) and generally considered to have been nuttier than a Christmas cookie, but also the most completely Cultural German Ruler imaginable. Aside from retaining a huge amount of autonomy for Bavaria within the German Empire, he's the one who patronized musicians, composers (notably Richard Wagner), artists, actresses, and built several palaces and castles (Neuschanstein is the best known, but Schloss Linderhof is a gem, and the Herrenchiemsee, though unfinished when he died, was set to Out-Versailles Versailles) which are now major tourist attractions (the most popular in Bavaria to this day).
Friedrich III (Friedrich Wilhelm Nikolaus Karl) Emperor of Germany for less than 4 months in 1888, but one of the all-time great What Ifs of history: a liberal Prussian monarch! Considered a very good general in the wars of German Unification 1862 - 1871 but also married to Victoria's eldest daughter, wanted to reform the German government into a cabinet-style constitutional monarchy similar to Britain with a severely limited Chancellorship, championed German Jews against persecution, vastly expanded art and museum collections in Germany.
With the exception of Ludwig, all of them have potential Militaristic possibilities, but none of them have to be defined (or should be defined) by those.
As for Unique Units, let's retire the U-Boat, please. Germany went all-in on submarines because she couldn't match her opposition in the 20th century in surface navies - it was the Poor Man's Navy alternative, and it utterly failed her in both world wars (in fact, since the U-Boat War brought the USA into the war against Imperial Germany in 1917, the U-boat could be said to have destroyed Imperial Germany: not exactly what you're looking for in a German Unique Unit!)
Possible German military Unique Units:
Landsknechts - I know, actually Holy Roman Empire, but also composed almost entirely of Germans
Reitors - 'light' cavalry with pistols, copied by almost everybody else in Europe.
Death's Head Hussars - (Prussian) (okay, actually only 1 regiment wore the 'Totenkopf' insignia, but it's too good a title to leave out) - the first Light Cavalry trained to charge in mass like heavy battle cavalry: again, copied by everybody else, but only after Prussia showed them all how to do it.
Assault Troops (Stosstruppen) - rthe WWI infantry that initiated 'infiltration' tactics, seeping through and round front line strongpoints to unhinge whole sectors of the front. Were it not for the USA's entry into the war, these might have allowed Germany to tweak out a victory in 1918.
