Definitely number 1 but I use
Edit: Well not exactly those but similar
This is my favorite starter jar. It's big enough to accommodate 300 grams of risen starter, and easy to see how much it rises.
I found a taller version of the ball mason jars that are 24 ounce. This should enable you to raise the basket within the jar and spin off most of the solvents.

It really doesn't matter. But my favorite jar to use is this tall wide mouth ball jar. I like it because I can more accurately gauge how much my starter has grown since it isn't as wide as those weck jars, And it's still big enough to hold 300 g of starter after more than doubling in size.
I absolutely love my tall straight sided ball jar. It's big enough for about 300g to double in size which is plenty for what I do. Ball 24 oz Jar, Wide mouth, 24 ounce (Pack of 2),Clear https://www.amazon.com/dp/B0725J3TXM/ref=cm_sw_r_apan_glt_i_VYZ4V05EG3MEXBNSPP5X

Its the right width and height and can be stored in the fridge in the same container.
Wide mouth mason jar has straighter edges and will be easier to clean, feed, and remove starter from. Like:
