I completely understand! Definitely not just you - I have a hard time too. When I got the 2.2mm band, it felt a little small at first, but I quickly ended up loving how versatile it is. Goes with everything - but I'd probably prefer just a tiny bit bigger/2.5mm :)
What about trying a couple inexpensive CZ bands first? Here's a 3mm under $15 that includes customer pics/videos: https://www.amazon.com/dp/B082ZC351S/ref=cm_sw_r_sms_awdb_btf_t1_M30NFb0X3TX33?_encoding=UTF8
Or this, 3mm but channel set: https://www.amazon.com/dp/B00MLR6626/ref=cm_sw_r_sms_awdb_btf_t1_n30NFbV30FA13?_encoding=UTF8
Here's a 2.5mm but it's also channel set - not finding many 2.5mm on Amazon in different styles for some reason: https://www.amazon.com/dp/B07QFS6SBC/ref=cm_sw_r_sms_awdb_btf_t1_Ug1NFb8MEAHDG
