I guess that would give a definite answer to this. Please try it if it is not too much trouble.

Is it dangerous to charge the macbook with a 65W PD Monitor?

I leave it always plugged in and then open the lid if it’s powered down completely. Generally I keep it in sleep during the weeknights and completely powered down during the weekends. It’s literally ONLY used for work. Everything else I do on my 14” and on battery power more often than not.
OK so I used 30 watts Magsafe vs 96 watts USB-C and it uses the higher power adapter regardless of order (it doesn’t prefer Magsafe). That sounds good to me. I can’t remember if I tried out the same on my old USB-C only MacBook Pro and it was just staying on the first one. I do think Apple Silicon MacBooks have more advanced battery and charging abilities, like you don’t have full battery health capabilities on any Intel Macbook but Apple Silicon ones do.I guess that would give a definite answer to this. Please try it if it is not too much trouble.
OK, sounds reasonable it works that way. I guess it would work for me with MBP 14" since my USB-C PD monitor output 60W and Magsafe would be 67W so it would prefer it as I want.
I just booted up my work machine for the sake of comparison. Keep in mind the following:
1. I've had my 16" work machine since March 2022, but I've only had my personal 14" machine since about April 2022.
2. Optimized charging is turned on for both, but the work one is used primarily plugged in, and the personal is used about 70% of the time on battery and about 30% of the time docked/charging.
3. Work Mac is used only during the 9-5 work day and almost never on weekends. Personal Mac, vice versa.
Both machines list as optimal battery health with 100% capacity. The 16" has 8 charge cycles on it and the 14" has 14 charge cycles. I think that proves fairly well that a) the machine I'm using primarily on battery, as you'd expect, takes a hit in overall wear on the battery, b) the OS is doing a VERY good job maintaining a charge below 100% on the work machine, and c) the M1 Pro in each device is very, very efficient.
EDIT: Footnote to this--I just docked my 14" Pro, had all my normal apps open and my Time Machine drive plugged in for backups, and played Psychonauts 2 at "very high" settings for an hour or so. During that time, the battery charged back up to 100%. These machines continue to impress in so many ways. It's literally like having a hybrid desktop/laptop. FINALLY.

So your 16" has been plugged in for about 4 months now and not used on battery during that and yet it has 8 charge cycles already. So that would make around 25 charge cycles per year with about 40 hours of use per week when using it on charger. Not really much cycles for the battery but it proves that battery is not just disconnected when it is plugged in constantly but it is using it all the time.
No, not constantly. It does get used off the charger here and there and has been out of town for a week for a work trip where it was on battery most of that time. Many of those charge cycles are from that.
