due to narutos understanding of all universal things he can use all the tailed beast abilities even without them there because he can manipulte all nature manipulation and shape transformation, aslong as hes connected to the beasts, which he is.

1. narutos situation is unique its the first time we have someone become a jin with only a partial chakra and a full consiousness of the beast, so past expiriences with this doesnt really mean as much although i do think naruto is a mixture between two of your ideas 2 as mentioned before he can summon all the beasts and simply refule there chakra if neccessary although this takes time and chakra and preperation 3 one of our previous mentioned possibilities is that he has a set amount of chakra that he cant use just like he cant use all of kuramas chakra at one point kurama goes to sleep to refuel, in that sort of sense because chakra was important to there connection it would make sense that he has a permanent unusable portion and weather his chakra can be recharged depends on prehaps proximity or some other method or even that it cant be recharged remotely but he still retains all the abilities of the chakra since he still has access to all his kekkei genkai tho part of that could be because of his understanding of all creation ability

and one last possibility thanks to minato we know bijuu can be split and sealed. giving chakra to someone cant be refueled unless its dormant but if lets say 10 % of the bijuu chakra wasnt given but instead sealed into naruto then it would be able to regenrate, keeping in mind that kurama is "sealed in naruto but wihtout the eight trigrams seal in place anymore meaning the seal is open its possible there chakra was just put there and sealed in a similiar fashion
