Morocco would be... acceptable, though it wasn't exactly very spectacular or accomplished in the 19th century. I think Egypt would be much better, it was entangled in a lot of very interesting stuff in that era, plus we could finally see the islamic Egypt in game and have the historical Egyptian path through Abbasids.
Leaving industrialization aside and concentrating on an early onset of the third era, Morocco is actually a really good fit time-wise and being alongside America, Britain, and France would be thematically. Of course, you can also make a case for an earlier Morocco (or Almohads etc.), where corsairs and the rivalries with Spain and Portugal would fit nicely. Yet, that could also be a Tunisia of some sorts.
For Egypt, I agree that Muhammad Ali's Egypt is a very interesting period, and maybe more so than the following Kingdom. Yet, a truly independent representation, not focused on Westernization, could be even more interesting, especially if it interacts with legacies and artifacts in an interesting way.
Generally speaking deciding between exploration Ottomans and modern Ottomans would be a horrible dilemma for me, there are very good arguments for both. Modern Ottomans can finish the path and fight ww2, but exploration Ottomans can fight Byzantium and Spain, Franks, Bulgaria, potentially Hungary, Austria, Poland etc. They'd also be the Islamic civ with the element of naval exploration.
I would really be super surprised if Ottomans don't make it to the modern era. The "rivalry" with Byzantium is probably more important for outsiders than for people interested in the Ottoman culture, who would want to highlight the centuries to come instead of the ones before. Their rivalries with Spain and Austria, and their alliance with France can/should also fall into the modern era in civ – and I think this is also where Austria will go, tbh. So, you only loose Bulgaria, Venice, and Spain as opponents, but you gain the other two gunpowder empires, and a host of others that were important in the years between 1500 and WWI.
Fun Islamic naval exploration civs are to be found on the coasts of East Africa (Kilwa, Ajuraan) or the Arab peninsula (Yemen, Oman), for example. And whatever Maghreb civ in exploration would probably also have a naval focus.
