I have no idea what to build next in Minecraft:
What I already have:
2 large houses and 2 small houses
tree house
lake
Nether portal
Ender portal
Beach
Wheat farm
I'm currently planning to build a bunker and a lava lake and need a few more ideas.
I have the Java Edition. When I build, I always switch to creative mode and when I play properly, then survival mode.
How about a bunker under the lava in Nether? You can do that by removing them with a lot of gravel. Take a look at a YT video.
Build an adventure map
On this website you can get / search for other ideas: https://www.minecraftmaps.com/
Why are you switching between creative mode and survival mode? This means that you can't collect any achievements. If you switch between peaceful and normal in survival mode, for example, you can continue to collect achievements.
Have a look at Larslp, is a Youtuber who presents ideas and tutorials.
Because you might. First something would like to build up and then would like to play in this world?!
I change the mode all the time and have experience 35. I also mine things in survival mode to get exo
I understand that

Well, yes, but then you can no longer collect successes. Better to build on something peacefully in survival mode and then switch to the normal level of difficulty.
I switch modes all the time and have experience 35.
I think you don't know what Minecraft Achievements are.
Leveling through experience points has relatively little to do with success.
To give just a few examples, some Minecraft successes are "Inventory", "Knocked on wood three times", "Build a workbench", "Get lucky!" "Start plowing" and so on. You can find a correspondingly extensive list https://minecraft.fandom.com/de/wiki/Erfolge.
However, if you start a Minecraft world in creative mode, or switch to creative mode in a Minecraft world, or if you allow cheats when creating a Minecraft world, no fulfillment of conditions for such successes will be assessed, which means that you can't collect these successes, at least with regard to the Minecraft world in question.
You don't need success either!
As long as it's fun, it's good, you can only play creatively, then it's just boring
Yes, it is really boring, but it can also be if you play it peacefully in survival mode. And at least you can play pretty painlessly and only have to pay attention to the health of the character in terms of lava, water, air and hunger, but then you won't be attacked by mobs.
