Yes, everything seems ok, phpMailer is installed; i am not sure about code minification modules (HTML, JS and CSS Minification v1.0.0) is not installed yet.
And i´m not on php 8.x until now, i have 7.4.33 and this looks good.
The shop is not "live" at the moment, but we have to go live april, so i hope to change to php 8 until then, but i do not use a standard theme and i am really not sure if it works with php 8.
