I've been to the Maldives about a dozen times.
I don't know much about their human rights violations. Not many people do because, with one or two exceptions, foreigners are generally not permitted to visit the islands that are inhabited by the Maldivians. You can only stay on resort islands where the only Maldivian residents you will encounter are the resort staff. The only places where there is a mixture of tourists and Maldivians are the capital island, Malé together with the adjacent Hulule island on which the main airport is situated. Neither of these are tourist islands but two thirds of the Maldivian population lives on Malé and it is open to visitors. There are also some islands in the southernmost Addu Atoll. Here lies the island of Gan where the UK had a base until 1976 and there are about six or seven large islands connected by causeways. This area is quite unlike the rest of the Maldives. The islands are larger, there is an airport on Gan and the former UK naval and air base has been converted to tourist accommodation. On these islands tourists can have a roam round and encounter locals. There are also one or two tourist islands which have a nearby residential island and I visited one during one of my trips.
Unless things have changed dramatically since my last visit (in 2011) then I cannot possibly see how the country meets normal standards of human rights. The population is fiercely controlled. People cannot travel between islands without permission, they must work where they are told to, I would estimate that over 95% of women do not work. There are jobs available but they all seem taken by men. The only working women I saw were a few in the resorts, usually on "front office" type work and some at the airport. It is a 100% Muslim nation and despite virtually their only source of foreign income being tourism, they don't really greet their guests with the welcome you see in other parts. Of the few genuine locals I have spoken to (as opposed to resort staff, many of whom hail from India, Sri Lanka and Bangladesh) most of them seemed to resent the way tourism has encroached on their country to such a degree. I cannot honestly see how their return to the Commonwealth will provide much of a boost to the UK.
