I know very little about SMPS and need to make a reliable SMPS with these data.
Input voltage can vary from 230VAc to 500Vac (230,380,440,480 500).
Output should be 24VDC at 2A.
All schematics or tips are welcome.
THanks for your help.

input voltage 150V will consume about 0.6-0.7 amp.
for 220-240V input, current is lower (about 0.5-0.6A)
if we assume current consumption are 0.7A, and voltage change (peak value) 300-210=90V
then C will be :
C = (0.7/90) 20(ms)= 155uF
you can use 220uF/400V
Note: all above values are approximate.

I think it depends upon application, but with LNA you achieve better sensitivity (lower noise figure), but as you noted, bandpass filter are necessary in either case to remove out-of-band strong signals, which could end up in your intermediate frequency without it...

Your largest risk will be safety. This will be probably powered from the AC mains and has the potential to rise to high temperatures or electrocute you if it is not designed properly.
I would suggest that you hire the degaussing from a competent source instead of building the equipment yourself.
