So youre getting close to those big final quests and wondering about the timing let me help you out with that. I've been through this part a few times and its definitely worth taking a breather before jumping in. Those main story missions like through time and space and battle preparations, they tend to roll pretty quickly into each other once you start them and trust me, you dont want to miss out on any good side content.

Good to know: what i usually do is wrap up all the character focused stuff first, especially things like reason of state if youre interested in how the political situation plays out. Theres quite a bit of content that can get locked out once you dive into those final missions with ciri and the wild hunt, so its worth taking your time to explore and finish up contracts youre interested in.

The good news is that after you finish everything and roll credits, you can actually jump back in and keep playing, though some of those story heavy side quests wont be available anymore if they were tied to pre finale choices. Take it from someone whos rushed through before its definitely worth getting everything sorted before tackling those final missions, makes the whole ending feel more complete that way.
