Both languages require care and diligence, and an intuitive understanding of
their memory models (which overlap a bit).

All languages do.

I've spend decades working with C and C++, and am very comfortable with them.
I still google or read up on various solutions, just to be sure I've got the
best or newest solution in mind.

This is one of the most important benefits of C++:

    https://en.cppreference.com/w/cpp/language/raii

    Resource Acquisition Is Initialization or RAII, is a C++ programming
    technique which binds the life cycle of a resource that must be acquired
    before use (allocated heap memory, thread of execution, open socket, open
    file, locked mutex, disk space, database connection—anything that exists in
    limited supply) to the lifetime of an object.

    RAII guarantees that the resource is available to any function that may
    access the object (resource availability is a class invariant, eliminating
    redundant runtime tests). It also guarantees that all resources are
    released when the lifetime of their controlling object ends, in reverse
    order of acquisition. Likewise, if resource acquisition fails (the
    constructor exits with an exception), all resources acquired by every
    fully-constructed member and base subobject are released in reverse order
    of initialization. This leverages the core language features (object
    lifetime, scope exit, order of initialization and stack unwinding) to
    eliminate resource leaks and guarantee exception safety. Another name for
    this technique is Scope-Bound Resource Management (SBRM), after the basic
    use case where the lifetime of an RAII object ends due to scope exit.
