Probably the better solution. It is an understatement how hard it is to get out of the commercial licence. If you would find out later that it isn't for you (or the Qt Company raises their prices again, like what happened from v5 to v6). You even require written permission from Qt to upgrade from LGPL to the Commercial License[0].
