Well, a frequent theme is the discovery of new magic. The female Merlin character usually has some knowledge or power that is new to the Harry Potter characters. This leads to exploration and adventure as they try to understand it together. Also, there's the theme of destiny. It's often portrayed that these two are meant to be together, like their fates are intertwined in the grand scheme of the magical world.
In these fanfictions, a common theme is the role of the female Merlin as a catalyst for change in the Harry Potter world. She might introduce new spells, ways of thinking about magic, or solutions to problems that the regular characters haven't considered. And of course, the theme of love and attraction is always there. It shows how two characters from different magical heritages can fall in love and how that love affects the world around them.
One common theme is the clash and combination of different magical systems. Since Merlin comes from an older, perhaps more archaic magical background and Harry Potter from a more defined and structured magical world in Hogwarts. Another theme is mentorship, often with Merlin as the wise old figure guiding Harry.
One common theme is the transfer of power. Since Merlin is a very powerful wizard, when he reincarnates as Harry Potter, there's often a focus on how Harry now has access to that power.

Harry's original destiny in the Harry Potter series gets intertwined with whatever new path Merlin's reincarnation sets for him.

Another theme is the discovery of self. As the reincarnated Merlin, the character has to figure out who they are and what their purpose is in this new world.
The exploration of magical heritage is a significant theme. Harry has his own complex magical heritage, and Merlin is a figure deeply rooted in magical history. Fanfiction may explore how their heritages are related or could influence each other. For example, it could be discovered that Harry has a distant connection to Merlin's line. Additionally, the theme of friendship and loyalty is common. Writers might depict how Harry and Merlin form a strong bond of friendship, and how that loyalty is tested in the face of various challenges in the magical world.
Power and responsibility is a big one. Since the character has a connection to Merlin, they have to deal with the power that comes with it and the responsibility to use it well. Also, the exploration of ancient magic and how it fits into the existing Harry Potter magic world is quite common.

Family secrets also play a big role. There are often hidden aspects of his family history that he has to uncover. Additionally, there's the theme of acceptance. How does the wizarding world accept or reject Harry once his true parentage is known? It can lead to some really interesting social and political dynamics within the wizarding community.
In these fanfictions, a recurring theme is the adaptation. Fem Merlin has to adapt to the new rules, new culture, and new social environment of the Harry Potter universe.

There's often a conflict as they try to be together, like hiding her true nature from the wizarding community.

Since both Harry and Merlin are associated with magic, fanfictions often explore different aspects of magic, like how they can combine their powers or learn from each other's magical abilities. Another theme is friendship. They come from different time periods but still form a strong bond in many stories.
