This is a follow-up question to Which projection when dealing with least-cost path estimation across the Mediterranean area?. The Europe Lambert Conformal Conic has been suggested by @Fezter.
Shall I customize the projection modifying the two standard parallels in order to best match my area of interest?
In fact, I am not interested in the whole Europe, rather in its southern-most part, i.e. the Mediterranean basin (let's say from Gibraltar to Cyprus [west-east], from Corsica to Lybia [north-south]).
