I think Barcelona achieved a good success by eliminating Napoli. This year, they are in the race for second place in the league together with Girona. I don't know who will win this race, but I think what is more important for Barcelona than La Liga is to win the Champions League. They will be extra motivated for the Champions League and want to beat the other match. Real Madrid, on the other hand, will most likely finish the season as the leader without any surprise losses.
Barcelona managed to end their long wait after since 2020 they failed to reach the quarterfinals of the Champions League, victory over Napoli as well as proving that Barcelona still cannot be underestimated when playing in the Champions League, for now one first step for Barcelona to compete again in the race for the Champions League title even though we know the opponents they face later in the quarterfinals are strong teams.
While their chances in La Liga to compete with Madrid are over and the main focus for Barcelona apart from ending the season as far as possible in the Champions League is of course finishing above Girona or being second in the table is the main target for Xavi before he steps down at the end of the season, I think for the La Liga championship trophy this season has been in Madrid's hands and it is difficult for Barcelona and Girona to seize because indeed Their position that has been far behind, besides that next season will be fantastic for Girona who did appear quite surprising this season, Girona who have performed brilliantly throughout this season have the opportunity to appear in the Champions League next season for the first time.
