JWTs are a widely used method for secure data transmission between parties. Although beneficial for API authentication and inter-service communication, JWTs pose challenges, especially in sessions due to token invalidation and storage issues. For secure use, store JWTs in HttpOnly cookies and utilize HTTPS. Consider alternatives for session management to address the limitations and potential security risks associated with JWTs.

Its a good read, but for the most secure use dont store the JWT at all, use it in-memory and implement a refreshToken and store that one as a HttpOnly cookie with samesite to strict and secure to true.
That way when the state reset due to browser refresh and cant find a jwt or it has expired due to the short living nature of jwt, a valid refreshToken will issue a new jwt while invalidating the previous refreshToken and generate a new refreshToken, and from now on its a repeat cycle of checking if the user is Unauthorized if so check RefreshToken, refreshToken valid generate new jwt and invalidate the previous refreshToken and generate new.
That is the best way i have implemented a secure jwt.

Also its a good practice to store a jwt and refresh token in an encrypted format, this way add more security as jwt can be decrypted easily, just try to paste your jwt on <a href="http://jwt.io" target="_blank" rel="noopener nofollow">jwt.io</a> you can see the magic
