If possible I like floor and shower walls to look like a continuation from one to the other . I rarely like 24 x48 tile for exactly the issues you are now having since none of the sapces are suitable for thta large tile IMO Of course now you have the tile so have areally good talk with the tile setter to avoid the issues that you are facing. FYI if no tile yet I suggest 12 x24 and also thta space is going to need a fabulous tile settert o get right . Many do not do enough large format tile to do agood job. I am thinking to start the tile at the far wall layed stacked and have the odd shape at the entry since honestly in this case the entry is not what you see first.

for me, a stacked look MAY/will show any off level placement more than a staggered application. They are naturally not perfect, so every tile has the potential of throwing off the line. DRY FIT everything.

I absolutely hate a beautiful tile job with slivers of tile, anywhere.

Fit everything so that your smallest cut is at least half of the original size tile.

Yes, it takes a lot of thought and measuring, but you are only going to do this once.
