This (unofficial) Adafruit Lithium Polymer Battery comparison chart and size list has every single Li-po battery as of the current date of August 24, 2021 (08/24/2021), excluding the battery packs. Those are cylindrical, so I didn't think it would fit in this list.
Note: It is important to keep in mind that the size/height are different in the website and the datasheet (located in the details section in the product pages). Also, clicking on the pictures lead to the product page. I took mine from the product pages. Also (quite a few notes I guess), the sorting might not work too well. Lastly, the table is using Datatables (MIT) if you were wondering.
