FWIW...
The P365 has been a #1 seller for a few years now. Likely due to some good reasons.
There are currently 3 combinations. Standard, X, and XL.
Modularity is a "plus" with the P365...meaning owning either/all of the 3 combinations can be "morphed/built" into any of the others. The standard slide fits the XL frame. The XL slide fits the standard frame...etc. In fact, the "X" is a standard slide on an XL frame.
Owning both a "standard" (although technically an SAS - ported barrel/slide) and an XL allows me to "mix and match" any slide with any frame.
Some key points that are "valuable to ME"...
The standard uses a 10 round capacity magazine (good in "current" restricted states). However, the standard also accepts the 12 round and 15 round magazines.
The XL frame has..."flush fitting 12 round magazine" and drops free. "Flared magazine port" (easier insertion). Extended beavertail frame (protecting the web in a "high hold" from slide bite). Straight trigger. AND slide cut out for Red dot optic.
That is a lot of plusses to me. Including the use of 10 round magazines in the XL (with floor plate adapter) for states with capacity restrictions.
Regardless of ones preferences...the P365 tics off a lot of boxes.
If you deicide to go that route, reach out...I have a few recommendations on peripherals that are useful to me.
