I use this to launch Lf (in lazy.nvim config format):

      {
        "<leader>f",
        [[<cmd>FloatermNew --name=Lf --title=Lf lf -command 'map l open' -command 'map o ${{open $f}}' %<cr>]],
        desc = "Lf",
      },

I have this hack for clearing old buffer when I renamed in Lf

      vim.api.nvim_create_autocmd("TermLeave", {
        group = augroup("lf-rename"),
        callback = function()
          for _, buf in ipairs(vim.api.nvim_list_bufs()) do
            local fn = vim.api.nvim_buf_get_name(buf)
            if not vim.bo[buf].readonly and fn ~= "" and vim.fn.filereadable(fn) ~= 1 then
              local success, msg = pcall(vim.api.nvim_buf_delete, buf, { force = true })
              if not success then
                print("Error deleting buffer: " .. msg)
              end
            end
          end
        end,
      })

I create a file call a.txt, open it, and then rename to b.txt. It takes a couple seconds for the new window to appear. I did profile like so:

:profile start profile.log
:profile func *
:profile file *
" At this point do slow actions
" :Lf
" rename a.txt to b.txt
" exit Lf
:profile pause
:noautocmd qall!

Open profile you can see:

I think checktime shouldn't be called here. It should be an option to enable at best or users should configure base on their own cases.

would be great to have a user command that fires on Floaterm exit?
