There is always this motif in Naruto how we should love person for his good personality even if that person is a dangerous weapon who is easy to get us hurt by it's emotions...Logically Naruto was worse choice to harvest Kurama since he is unable to control his emotions and his emotions got Kurama almost get out multiple times...Good Jinjuriki is calm and don't let his or her emotion disrupt control over tailed beast while Naruto is type of person who's emotions easy cloud his mind and emotions easy overtake him...
i mean, minato didn't have time to find anyone good (except he could've put it back in kushina but whatevs) and once naruto got the seal there wasn't much they could do after that, when a jinchuuriki loses their beast they die (unless the beast gets put back before death as seen with naruto in the war)
