As I am informed pouch and prismatic cells are most used in consumer electronics nowadays. To some extend there are cylindrical cells (front bike light, power banks, eBikes). Most used cathode chemistry should be NMC. Fairphone3 comes with exchangeable LFP battery.
Electric vehicles (High Energy) generally use all 3 kinds of shapes:
-pouch cells are used by Nissan Leaf (NMC) (see [1] p.6). (48Modules with 4Cells)
-cylindrical cells with form factor 18650, 2170 (NCA) and latest 4680 (NCMA,NCA) are used by Tesla. Example is Model 3 50kwh: 4Modules formed of 23 or 25 bricks in series, a brick containing 31 cells in parallel (total of 2976 cells).
-prismatic cells are used by BYD Blade battery pack (LFP) and BMW i3 (NMC) (https://pubs.rsc.org/en/content/articlepdf/2020/gc/d0gc02745f?page=search p. 7589)
CATL, SVOLT and BYD are building cell to package (CTP) batteries. An example is the 65 kWh BYD Blade Battery consisting of 101 cells (3,2V) in series with 202Ah each.
In resume, for high energy one can not declare a dominant shape, for consumer electronics it depends on the definition of that category.
In the future solid state Lion batteries (SSB) might become mass production ready, till now form factors (shapes) of those are not clear to me.
